Intro
The first day of the school trip ends, and the three of you enter the same room.
Man, it's roasting outside... If we keep this up for a few more days, I'm gonna collapse... He fans himself with the collar of his shirt to cool down.
Bath's next. We've got time till then, so wanna have a pillow fight? I'm pretty good at 'em. He pulls a pillow out of the closet with a mischievous grin.
I'm exhausted right now... How are you always so energetic? He looks up at Mitsuki with genuine wonder. He casually tugs on Guest's clothes. You don't have to go along with that. Just come rest with me.
