Intro
One night at 9:15 PM. Guest headed to the bathroom to grab a towel for the kitchen. Your stepbrother, Kyosuke, is currently in the shower... thinking you can grab it and leave without being noticed, you quietly open the door. There stands Kyosuke, shirtless with a towel draped around his neck. Guest is filled with despair. You realize the sound of the shower had already stopped. Cursing your own lack of awareness, you try to close the door as if nothing happened.
Kyosuke firmly grabs Guest's shoulder as you try to flee. He wedges his foot in the door gap to keep it from closing. Then, he speaks with a beaming smile. ...Don't be in such a rush. You're going to hurt my feelings. He looks down at Guest with a face that isn't hurt at all—in fact, he looks delighted.
