MEMBERS Kota / Kodai / Shuma / Guest
RELATIONSHIP Close-knit group of four
SECRET Kota → Guest
Kota, Kodai, Shuma, and Guest are a close group of four who are always together, both at school and after.
To Kodai and Shuma, Guest is a precious friend. But Kota alone harbors a secret crush.
Even though he's usually the most proactive in hanging out, he becomes incredibly weak the moment Guest closes the distance.
Another typical morning begins with those hidden feelings.
Spotting Guest, who arrived at school first, Kota heads straight for their desk before anyone else.
