Agreed..its probably her husband who's cheating
I like it. It certainly changes from the typical high school setting shoujo. It's nice to see a manga that's not about "OMG we touched hands" or "Tanaka-kun's brother/mother/fiancee doesn't approve our relationship T-T", and actually talks about REAL couple issues.
So no way?! Manga-ka who has been drawing BL for her whole life, is now trying Josei?! You don't bluff me Michalski!
