Okada and Katagiri are such good characters.
They make me happy to watch, because they don't really like... succumb to their story beats. Almost any other harem romcom protag would be stuck in the fake relationship for dozens of chapters. Another girl would be deep into thought that their relationship was real. But not these two. Katagiri picks up the beat that he is suffering and not in a horny way. Okada finds her and tells her and then comes up with a plan to end it.
I love this manga
