If Hana hadn't called twice, sent three voice notes, and then texted If you cancel on my daughter's birthday because you're tired, I'll never forgive you, I probably would have stayed home, locked the door, and ignored my phone until morning.
Instead, I carried a gift bag in one hand, a container of cut fruit in the other, and my bad mood up three flights of stairs while Mina skipped ahead and Jun followed behind me with the expression of someone being punished for a crime he had not committed.
By the time Hana opened the door, I was out of breath.
She took one look at me and laughed.
"You came."
"I need wine," I said.
"You need several things, but yes, I can do wine."
That almost made me smile.
She stepped aside to let us in, took the fruit from my hands, and leaned down to greet the children before pointing them toward the living room.
The apartment was already loud.
Children ran past in socks. Someone had turned the television up too high. A burst of laughter came from the kitchen, followed by the sharp crack of a soda can opening.
I handed Hana the gift bag. "This is for Sora."
"You didn't have to bring anything."
"I know. That's why I resent it."
She laughed and bumped her shoulder against mine. "You look nice."
"I look tired."
"That too."
Then, lowering her voice, she said, "My husband invited a few people."
I stopped halfway through taking off my shoes. "What people?"
"People. Don't make that face."
"Hana."
"It's a birthday party, not an ambush."
That was exactly what someone staging an ambush would say.
Before I could answer, Mina disappeared toward the living room, drawn by sugar and noise, and Jun drifted after her with all the visible enthusiasm of a hostage.
Hana watched them go, then grinned at me. "Your son has your exact expression."
"Cruel."
"Accurate."
Before I could say anything else, a man appeared beside her carrying a carton of juice pouches.
He was the kind of man women noticed first.
Tall, neat, well-dressed in the effortless way that usually meant expensive. His sleeves were rolled neatly, his hair was in place without looking arranged, and his smile came too easily to be anything but practiced.
"Yuna," Hana said, "this is Minjae. He's a friend of my husband's."
Minjae shifted the carton to one arm and offered me his hand. "Nice to meet you."
I shook it. "You too."
"Hana said you'd be coming with your kids."
I glanced at her. "Did she."
"She also said you'd look like you were considering escape."
"Hana says many things she should keep to herself."
"Only because they're true," Hana said.
Minjae laughed.
It was unfair how quickly some people became charming.
"I was told to help," he said. "So if you need someone to carry anything or rescue a child from a sugar-related emergency, I'm available."
Hana leaned closer and murmured, not quietly enough, "And he's single."
I almost closed my eyes.
"Hana."
"What?" she asked innocently. "I'm introducing people. That's friendship."
Minjae, to his credit, looked amused rather than embarrassed. "I promise not to make this awkward."
"That makes one of us," I muttered.
He laughed again.
I understood him immediately.
That was the thing.
Men like Minjae were easy to place. Warm. Polished. Social. The kind of man your friends approved of before you had even formed an opinion.
The kind of man women were supposed to notice.
He glanced toward the kitchen. "Do you want me to take that?"
I handed him the fruit container. "Thank you."
"My pleasure."
He disappeared down the hall with Hana, and I stepped farther into the apartment at last.
There were balloons tied to chairs, silver ribbons curling from the light fixture, cartoon plates stacked near the dining table, and two cakes already waiting under clear plastic covers. Someone's toddler sat on the floor crushing chips into the carpet with frightening concentration.
Jun had already found the farthest corner of the room and stationed himself there with a can of soda, looking personally offended by celebration.
At least he was participating by location.
I was still taking in the room when I saw him.
For one stupid second, everything in me went still.
He was standing near the window now, half-turned toward a young woman sitting in a chair beside him. One hand held a paper cup. The other rested lightly against the back of her chair as he listened to something Hana's husband was saying.
Dark hair. Still face. Controlled posture.
Joonwoo.
He looked up before I could look away.
Not startled. Not warm. Just steady.
Like he had noticed me the moment I walked in and had been waiting to see if I would do the same.
My chest tightened so suddenly it made me angry.
I had met him once. Briefly. In a grocery store aisle over milk and oranges and nothing that should have mattered afterward.
And yet there he was, standing in the middle of a room I had entered to eat cake and leave early, looking as if he belonged there in some permanent way.
The young woman beside him said something softly, and his attention shifted to her at once.
He bent to hear her better.
The gesture was small. Automatic. Intimate in a way that told me they knew each other well.
I looked away first.
"Yuna."
Hana's hand landed lightly on my arm. I hadn't even heard her come back.
"You haven't met everyone properly yet."
"I'm not staying long."
"That wasn't the question."
Before I could stop her, she steered me farther into the room.
I should have resisted.
Instead I let her guide me through the clutter of children and balloons and adults balancing paper cups, my pulse behaving in a way that felt both embarrassing and deeply inconvenient.
Minjae appeared again just long enough to pass Hana a stack of napkins. She smiled at him, then at me, with the kind of expression that made me instantly suspicious.
"Yuna, you already met Minjae," she said. "And—"
She lifted her voice slightly.
"Joonwoo."
He turned fully then.
Not quickly. Not reluctantly either.
Just with the same calm he seemed to do everything with.
He set his cup down beside the cake boxes before walking toward us.
That small distance should not have felt like anything.
It did.
Hana touched my elbow. "This is Joonwoo. He and my husband have been friends for years."
Years.
That word made him feel more real than he had in the supermarket. Less like a strange encounter. More like a man with roots in rooms like this, with a life that intersected other people's in ways mine apparently never had.
"We've met," he said.
Just that.
No smile. No explanation.
Hana looked between us. "You have?"
"Briefly," I said.
Why did my voice sound like that?
Hana, oblivious as ever, laughed. "Well, that saves time."
Then she glanced over her shoulder and said, "Lian, come here a second. You too. I'm doing proper introductions before this party ends and I forget my own name."
The young woman near the window looked up at once.
Up close, she was even younger than I had thought from across the room.
Not a girl. Not exactly. But young in the way some women still looked untouched by the harder parts of life. Her hair was pulled back loosely, and there was something soft and careful about her face that made her beauty feel almost accidental. One hand curved over the roundness of her stomach as she rose.
Pregnant.
The sight of it landed in me a second too late and all at once.
She came toward us slowly, and before I could stop myself, I noticed that Joonwoo had already shifted slightly toward her.
Not enough to be obvious.
Enough to make space.
Enough to make sure she didn't have to step around a balloon ribbon lying across the floor.
"Yuna," Hana said, smiling too brightly, "this is Lian."
Lian smiled at me.
It was a soft smile. Open. Uncomplicated.
"Hello," she said. "I've heard about you."
That caught me off guard. "You have?"
Hana answered before she could. "Only that you're my most difficult friend."
"I prefer selective."
"Difficult," Hana repeated.
Lian laughed quietly.
Even that sound was gentle.
"I'm glad you came," she said. "Sora talks about Mina all the time."
I looked at her properly then.
She didn't seem sharp enough to dislike on sight.
Didn't seem polished enough to resent.
There was a tiredness around her eyes that pregnancy had not softened, only made more delicate. She looked like someone who said thank you to waiters and meant it.
The worst kind of beautiful. The kind that gave you no right to be unkind.
"I'm glad too," I said, because she deserved politeness and because anything else would have made me look as strange as I suddenly felt.
Hana clapped her hands once. "Good. Everyone knows everyone. My work here is done."
"That's a lie," Minjae said. "You've been assigning labor for the past twenty minutes."
"That's because none of you are naturally useful."
He laughed.
Lian smiled again, then put a hand lightly against her lower back in a gesture that looked more reflexive than dramatic.
At once, Joonwoo looked down at her.
"You should sit," he said.
His voice was quiet.
Not tender exactly.
Something more dangerous than that.
Familiar.
She shook her head. "I'm fine."
"You've been saying that for an hour."
"And I'm still right."
Minjae grinned. "This feels like a private conversation I've been unwillingly invited into."
Hana rolled her eyes. "Then go carry something."
He saluted with two fingers and wandered off toward the dining table.
Lian smiled, a little apologetically, and said to me, "He worries too much."
The answer came from Hana's husband instead. "No, he doesn't. You just pretend you're not tired until you nearly fall asleep sitting up."
Lian made a face at him.
It was small.
Almost shy.
And suddenly I understood something humiliating and immediate.
She belonged here.
Not just in the apartment.
In the shape of everyone's attention.
In the rhythm of their familiarity.
And Joonwoo belonged to her life in a way that should have settled something inside me.
It didn't.
A child shrieked from the living room. Someone called for more plates. Hana was already turning away again, pulled by ten different needs at once.
"Talk to each other," she threw over her shoulder. "Try to be likable. I'm busy."
And just like that, she left me standing there with them.
Lian shifted her weight and looked at me with that same quiet warmth. "Do your children like school?"
The question was so ordinary that for a second I almost laughed.
"Yes," I said. "Mostly. My daughter likes everything. My son behaves as if joy is a personal insult."
Lian's smile widened.
Joonwoo's gaze flicked briefly toward me.
Not long. Just long enough.
"I've seen him," he said. "That seems accurate."
I hated the small heat that rose in my face.
Lian looked between us. "You really have met before?"
"Briefly," he said.
"In a supermarket," I added, before I could stop myself.
That made Hana's husband laugh. "That sounds unromantic."
No one said anything for half a second.
Then Hana, from the dining table, shouted, "Everything is unromantic after thirty."
The room laughed with her.
I did too, because not laughing would have meant too much.
Lian touched her stomach again and glanced toward the chairs near the window. "I should probably sit before he gives me that look again."
"He's already giving you that look," Hana's husband said.
"I know," she said, with the sort of fond resignation that belongs only to women who are used to being cared for.
Then she turned to me. "It was really nice meeting you, Yuna."
"You too."
She smiled once more and began to walk back.
Joonwoo stepped aside for her automatically, his hand hovering for a second at her back without quite touching.
That should not have mattered.
It did.
Then Minjae reappeared with a stack of paper plates balanced against one hip.
"Am I interrupting something solemn," he asked, "or are both of you just naturally intimidating?"
"Neither," I said.
"Both," Hana said from somewhere behind him.
Minjae grinned at me. "Good. I was worried I'd walked into unresolved history."
"There is no history," I said.
"Then there's still time," Hana said as she passed, and I nearly stared at her in disbelief.
"Do you want to die?" I asked.
"Not before cake."
Minjae laughed.
And because life occasionally enjoys cruelty in small, exact doses, when I looked up again, Joonwoo had seen me smile.
He didn't react.
That was worse.
He just glanced away first, returning his attention to the room as if whatever had passed through the air a second ago had not been worth holding.
A few minutes later, Hana hurried into the kitchen, flushed and smiling and carrying a pack of birthday candles.
"I need everyone's numbers before they leave," she announced. "I'm making a group for the photos because if I have to send them one by one, I'll stop speaking to all of you."
"Reasonable," Minjae said.
I reached automatically for my bag before realizing what she had said.
Numbers.
It was normal. Completely normal.
Birthday pictures. A group chat. Adults doing practical things after children had smeared sugar over every available surface.
Nothing about it meant anything.
Still, when I took out my phone, I felt rather than saw Joonwoo glance at me.
Hana grabbed a pen from the junk drawer and started writing names on the back of a paper napkin. "Yuna, yours first. Minjae, yours too. Joonwoo, don't pretend you didn't hear me. Lian, I already have yours."
From the living room, Lian called back, "You also have my doctor's schedule, my cravings, and my blood type."
"That's friendship," Hana said.
A few people laughed.
One by one, we read out our numbers.
That was all.
No secrecy. No excuse. No private exchange.
And somehow that made it worse.
A few minutes later everyone gathered in the living room for cake.
Children shouted. Adults clapped too loudly. Someone dimmed the lights and Sora burst into tears halfway through the birthday song, overwhelmed by attention in the exact way six-year-olds always were.
I stood near the back holding a paper plate I had no intention of eating from.
Lian was seated again by the window, and Joonwoo had taken the place beside her without seeming to choose it at all. He removed the overly sweet corner rose from one slice of cake before handing her the plate.
She looked at it and laughed softly. "I said I wanted cake, not a diplomatic compromise."
"You said you felt sick after sugar yesterday."
"I also said I was still going to eat it."
"You can eat the rest."
"That is not the same thing."
He took the fork from the plate, cut off a small piece with the frosting, and held it out to her without expression.
Lian smiled and accepted it.
The whole thing was so practiced, so ordinary, so quietly intimate that I had to look away.
Not because it hurt.
Because it should have ended something, and it hadn't.
Later, while adults moved around collecting cups and children began the slow collapse that came after sugar, I was clearing napkins from the dining table when Lian spoke to me again.
"You don't have to do that," she said, rising slightly from her chair.
"It's fine," I said. "I'm used to cleaning up after children."
She smiled. "Me too, soon, I think."
Her hand drifted over her stomach again in that absent, protective way women had when they were already in conversation with the life inside them.
For one awful second, I didn't know where to look.
"You must be excited," I said.
"I am." She glanced across the room automatically.
Not searching.
Finding.
Joonwoo was speaking to Hana's husband near the balcony door. As if he felt it, he looked over at once.
Lian smiled when she caught his eye.
The change in his face was slight.
Almost invisible.
But it was there.
Something gentler. Warmer. Unarmored for exactly one second before it disappeared again.
"Yes," she said quietly. "I am."
There was nothing cruel about her. Nothing false. Nothing I could resent.
That made it worse.
By the time people started putting on shoes and collecting sleepy children, Mina was sticky with frosting, Jun was carrying a party bag like it had personally insulted him, and I was exhausted in that deep-boned way that made speech feel optional.
Hana hugged me at the door hard enough to wrinkle my coat.
"See? You survived."
"Barely."
"You always say that and then stay longer than everyone else."
"That's because leaving with children is a military operation."
She laughed.
Behind her, Minjae was holding Sora's abandoned paper crown and someone else's car keys. "It was good seeing you, Yuna."
"You too."
"You should come next time without looking like you're planning your own funeral."
"I make no promises."
He grinned.
Then Joonwoo, a little farther back, said, "Goodnight."
I looked at him once.
Lian was beside him, one hand looped lightly through his arm. His other hand rested at her back.
"Goodnight," I said.
Nothing in his face changed.
That should have helped.
It didn't.
By the time I got the children home, found Jun's missing sock, wiped sugar off Mina's cheek, and got both of them into bed, it was nearly eleven.
The apartment was finally quiet.
I stood in the kitchen drinking tap water in the dark, too tired to think properly, when my phone lit up on the counter.
Hana made a new group chat.
I should have ignored it until morning.
Instead I opened it.
The first few messages were exactly what I expected.
Hana: Thank you all for coming ❤️
Hana: Uploading photos now
Minjae: Sora is clearly destined to rule us all
Hana's husband: Already does
Lian: She gets that from her mother
Hana: True
Then another message appeared.
From Joonwoo.
Your daughter was right about the frosting roses. They were important.
I stared at the screen.
It was in the group chat. Nothing private. Nothing wrong.
I was going to answer.
