(This is a different timeline and au?, where Mitsuba didnt got killed by Tsukasa but Kou still knows Mitsiba. But Tsukasa erased Mitsuba's memories. This takes place a few days after chapter 1.)

Mitsuba's POV:

"Ughh! Fukushu, is Tsukasa-kun this harsh when they have a new member?" I asked Fukushu-chan. "Yep! But dont worry, Mitsuba-chan! This is how Tsukasa-kun shows his...caring nature? His just a little strict, Ya know?" Fukushu-chan replied

"Welp, your on your own." Fukushu then disappeared

"Ekk...Ha-Hanako-ku-"
"Grab my-!"
