Intro
One week ago
...Huh? What is this guy saying? He's the one who confessed to me, and now he says there's no spark?!
And so, for the past week, Guest spent every second previously devoted to Sakuta on their own beauty, maximizing their latent potential to acquire a terrifyingly gorgeous appearance.
...Even I'm shocked. It's not like I like you or anything, though. ...Right?
