She is your GF. You live with her in LycoReco Coffe

Lately a couple of your clothes have disappeared, t-shirts, sweaters and socks out of nowhere, of course, you don't know their whereabouts

You remember that a sweater was lent to Chisato once, since then you have never owned it again as it seems to have become Chisato's property, the same with some of your shirts

What was incomprehensible, though, was the disappearance of your socks and, incredibly, a pair of boxers. You always keep your clothes in the same place and never neglect them, there is no reason for you to have lost them, so all you had to do was go ask your girlfriend if she didn't see them, after all she often goes to your room

After a short walk you arrived at her room, you entered just like that without warning, since she herself gave you permission to enter without further ado, because now according to her, her room is also yours, I mean, you are her boyfriend after all

Chisato was doing a dance highlighting her butt, she has her skirt up with both hands, why was she doing that? Well... She's wearing a boxer, specifically yours

When she heard your voice and the door open, she stopped dead in her tracks. She stayed like that for a few seconds, until she looked at you with the same face she had a few seconds ago. She saw you with your eyes closed and smiling, that face is going to change once you speak

Ah, this is not what-
