**Day 28 Morning Plains**
Currently fleeing from the inn, right now. Not like I'm posting updates or anything? I'm a loner, so I'm not even connected. To anyone. Hot cake!
Why? Why though? How come? My opposite-sex favorability is in critical danger! That class rep's glare is lethal! And I'm the one with bad eyes saying this, so it's definitely true! So noisy!
How did they find out? Why do I get yelled at? At this point maybe they don't even need a reason to yell at me anymore? How low is it? My favorability? Is it diving? Underground? Wait—is my favorability actually at the bottom of the labyrinth? How far did it fall?! My opposite-sex favorability! Fell so hard it created the labyrinth itself? Gotta hurry and rescue it!
There's a gatekeeper at the labyrinth entrance. My natural enemy. For some reason gatekeepers in this world get mad the moment they see me? My same-sex favorability is apparently low too. Whatever, don't need it. I tried submitting an application at the Adventurer's Guild, but they wouldn't let me in? Apparently? Level too low? No favorability? Grudge over overtime? Not an adventurer? No clue, but they refused.
Sneaking in alone would probably get noticed. Because when I'm alone I'm completely incapable of being sneaky. I'd get caught for sure.
If someone else was here I could stealthily tail them from behind. I've got "Invisibility Cloak," "Presence Concealment Lv7," and "Stealth Lv8." Should be super sneaky. But nobody's coming? Unpopular? Even though my favorability is supposedly down there? What, does my favorability have complaints? Is it such unwanted favorability that nobody wants it? What kind of treatment is this for my favorability?! It's opposite-sex favorability! What? That attitude? Unforgivable. Should I attack the town? Raid the Adventurer's Guild?
"Wait, why? Today? Isn't dungeon day, right?"
For some reason my classmates came pouring in? Why is everyone carrying ropes? Bungee competition? Sure, bungee jumping is like an adult rite of passage, but you guys just turned 16—you're still high-school second-years, right? Stepping into adulthood? Climbed the stairs to maturity? Went to Akemi-san's shop? Where is it? Please tell me.
"""Yep, he's here!!"""
"Eh? Why? This is mine, right? Isn't this labyrinth made because my favorability fell? Gotta go pick it up from the bottom? It's mine?"
What are they even saying? It's obvious.
"No? This dungeon has existed way before Haruka-kun even came to this world?"
Careless. Shallow thinking. Should've realized sooner.
"Wait—so even back in the original world, my favorability was already dropped into another world? And it filled up the dungeon?"
No wonder I felt like my opposite-sex favorability was completely missing even back home… It really was gone? Completely? …
"No, this dungeon existed before Haruka-kun was even born! And favorability doesn't turn into labyrinths! What kind of favorability is that?! Favorability becoming the Labyrinth King?!"
Unbelievable. My opposite-sex favorability was already in another world before I was born. That's why I was summoned here—to chase it. I mean, obviously I'd chase it. It's opposite-sex favorability. Mystery solved! Gotta rescue my favorability fast before it goes to the next life. Seriously, don't transfer people's favorability across worlds—I searched everywhere!
No wonder I couldn't find my opposite-sex favorability anywhere. It was missing since birth. Serious hot cake!
…

…
Everyone's filing in one after another.
I'm sneaking in after them.
Or rather, tailing them.
Ooooh! So this is a dungeon! An isekai labyrinth! What's the difference from a cave?! If I renovate it, could I live here? Save on lodging costs? Kinda don't like random people passing through though. Would I have to serve tea? Dungeon café? Could make good money?
"Pretty nice layout, huh? Kinda living-room vibe? Even has a basement?"
"""It's a dungeon! Not a house! You can't live here!!"""
"…First words upon entering your first dungeon are 'house viewing' style? Were you invited by the monsters? Are you a guest?!"
Apparently no good.
"But look—the entrance is pretty spacious, shape's long and narrow, bends in a U. If we keep the walls, hollow out sections, raise the ceiling a bit… could be really nice? Kinda?"
I think it'd be good though?
"Why are you starting design work the moment you enter the dungeon? What kind of craftsman are you? Asano Takumi-no-kami? In the palace? Here?!"
"Don't renovate the dungeon on your own! Floor 1 is just a straight path so it's okay… no, it's not okay, but from Floor 2 everyone's mapping it—if the labyrinth gets remodeled into a mansion we'll get yelled at?"
"That stairway isn't an entrance hall, and below isn't a basement—it's an underground labyrinth! You can't turn it into an underground mansion! Visitors would be shocked?!"
"Conquering a labyrinth means remodeling it? Planning to hijack the monsters' home? Huh? Looks like it might actually work?"
"No! 'Hmm…'—you're already designing! The dungeon's about to get dramatically after-renovated! Even the monsters would be shocked!"
"Yeah, my current place has a cramped entrance—expanding it was tough. It's open one-room style with no partitions."
"""The designing has started!! Run, labyrinth… wait, you can't run, labyrinth!!"""
Eh, can't help it.
"I mean, ever since coming to this world I've been struggling with the housing problem? It was rough? Building one would be… pretty nice?"
"""What did you come to the isekai for? Renovation?! Dramatic makeover!!"""
Felt like I'd get yelled at if I kept messing with things, so for now I just quietly smoothed out the floor. Stealthily.
"Somehow the walking's getting easier? Is someone already remodeling? Anyone?"
"Yeah, I feel mana behind that wall… rooms aren't starting to form, right?"
"The entrance stairs we came down look like an actual entrance hall now? Was it always like that?"
As expected from a cheat-holder group—they noticed even though I was sneaky!
"No? Look—labyrinths grow, right? Growth spurt? Kinda?"
"""No way a dungeon turns into a mansion! What is this dungeon aiming for?!"""
"Eh—world heritage status? Target? Kinda?"
Yeah, that could work. Tourism would boom.
"If tourists come to the dungeon that's bad, right? Why would tourists fight monsters while sightseeing? Tourist power-leveling?"
Selling monster senbei at the entrance—would that make money? Lure monsters with senbei then club them—tourists are scary.
"Remodel? More like—goblins are getting swallowed by the walls and floor? Monster house? Are we the monsters now? Dungeon where monsters fight monsters?"
"No! If you react you lose. Everyone's pretending not to see… poor goblins…"
"…House materials?"
"""Kyaaaa—don't say it!!"""
Seriously, so noisy inside a dungeon. They really need to learn some public manners.
"Ah! If we put a closet here, it could be a nice wall accent…"
"""We said no remodeling!! Why is there a closet in the dungeon we're exploring?!"""
True—if a closet appeared here the nudist girls might start stripping. If they strip their gear too it'd be bad—it's a dungeon…
"No need for wall accents in a labyrinth? People might think it's a trap?"
"Floor 1 is just a straight pass-through… no monster fights yet… why are we already this tired? Why?"
? The floor's flat now so walking should be easier, but apparently they're tired? Weird.
"Maybe add a slope down? Easier access to the basement? Flow-wise it'd be at the edge but…"
"""Don't build it! Don't do anything! If Haruka-kun turns this into a mansion everyone will move in! We'll end up fighting the intruders!!"""
Makes sense—for defense positioning and splitting invaders,
"…Then Floor 1 should account for defensive stronghold setup. Plus a living-room layout that allows side-pincer attacks…"
"""Nobody wants a living room like that! It's a living room but no relaxing! Constant battle-ready state! And stop hunting adventurers?! They're allies?! Why are we the ones guarding the dungeon now?!"""
Apparently no good. Hm? …Huh?
What's this?
Inside the wall?
Here? … Ah!?
