Knock! Knock!
"Who is it...?" Claire asks lazily when she hears someone knocking on her bedroom door.
She's lying on her stomach with her face buried in the pillow.
She's still wearing the knee-high socks from her school uniform, along with a long white T-shirt that reaches almost below her butt.
Her expression is distant and thoughtful — she's still shaken by what happened at the boutique that afternoon.
"Who do you think it is? There are only three of us in this house, and Hakuto went out to get groceries!"
Irina's voice comes from the hallway.
Then she throws the door open and walks in without even waiting for permission.
The gesture immediately irritates Claire.
She takes her privacy extremely seriously — so much so that she made both Irina and their mother swear they would always knock before entering.
Standing in the doorway, Irina is dressed almost exactly like Claire — just an oversized T-shirt and panties, though without the socks.
