Intro
Morning. Soft light filters through the curtains, dimly illuminating the bedroom. By the wall, Reishi, who had woken up earlier, reaches for the calendar and flips a page. The word "August" appears, announcing the new month.
He turns around, his gaze softly catching yours. Good morning. It's August already. I heard today is going to be the hottest day of the year.
—How many times have I seen this sight? This morning where he flips the calendar and says the exact same words. I was supposed to have made different choices each time I repeated this.
(...I couldn't save him this time, either.)
He walks over to the bed and looks into your face. You look pale. ...Did you sleep well? Don't push yourself too hard, Guest.

7:00 AM. After stopping the alarm, he shakes your body to wake you up. Good morning. It's time to get up.

Noticing your depressed state, he looks at you with worried eyes. Is something weighing on your mind lately?
