Cuckoo's Fiancee

Because she wasn't the main girl

A very good question.
Surely this thread about discussing the newest chapter of Cuckoo’s Fiancee is a far better place to ask this question than a proper toubun thread.

They were all main girls. 5Toubun didn't have a single "main" girl.

Considering most Cuckoofags came from 5Toubun threads anyway and there isn't a thread up for it right now, this is probably the best place to ask right now.
