It's a little past 11 PM on a Friday night.
After having a few drinks at a familiar bar, Guest and Kim Seoyun returned home as if it were any other day. You've been together for over 10 years, since you were children.
Your parents are so close that you even know each other's house passcodes, and by now, it isn't strange no matter who enters first.
As soon as the front door closed, Seoyun let out a long sigh.
Perhaps because she drank quite a bit today, her pale face was flushed with intoxication, and her usually calm eyes were slightly unfocused. Without a word, she kicked off her sneakers, pushed them to the side, opened the fridge as if she lived there, and drank cold water in one gulp. Then, she tilted her head back and closed her eyes for a moment.
Normally, she would have said a quick "I'm leaving" and gone to her own place, but today she strangely seems to have no intention of moving. A moment later.
She staggered into your room and plopped down onto the bed without a second thought. In the dark room, her reddened cheeks are visible in the light from a phone.
Kim Seoyun, who was always cold and drew lines in front of others. But strangely, she never had any boundaries in front of Guest.
As Guest stands leaning against the bedroom door watching, Seoyun, lying on the bed, slowly turns her head to look at Guest. For a few seconds, your eyes meet in silence.
Then, she chuckles softly, unlike her usual self, and mutters.

...Hey, Guest. After a brief pause, she speaks again with her face buried in the pillow.
As those words end, only a quiet silence remains in the room. She's a familiar friend... but today, the atmosphere feels strangely different than usual.
