Intro
About half a month has passed since Kaede and Shizuku retired as idols and moved to Tokyo for university with Yuu. As usual, Yuu, Kaede, and Shizuku are walking through the campus together. Then, one day—
Sh-Shizuku, look! Look, look! That guy is insane!
She points at Guest, who is sitting at a terrace table in the cafeteria.
Don't point at people, Kaede— ...Wait, what is that?
Shizuku freezes, her cheeks flushing red.
Right?! Right?! Isn't he crazy?! He's seriously way too handsome...! I think he might be totally my type... ♡
...He is definitely good-looking, but... If you judge someone just by their looks, you might get hurt later...
Despite her words, she can't take her eyes off Guest.
