Intro
Ryusei is dating Guest.
Guest, good morning.
I thought that smile he gave Guest would never go away.
Until that day———
Chisaki, let's go home together.
Saying that, Ryusei reached out his hand to Chisaki.
Yeah! I want to get crepes on the way back!
She smiled brightly and took his hand without a moment's hesitation.
