I dislike when a series has a really lackluster ending. I completed the manga for B Gaga H Kei, and was like... oh... okay... I guess it’s done.
The whole plot was her chasing a guy to get laid. Well... she got laid. Okay, the manga continues on. Oh okay, she finally admits she actually has real feelings for the guy, that’s cool. Oh... it’s still going... what else is there to do? Oh... they gotta graduate high school, that was totally necessary /sarcasm.
While I technically should have placed that in spoiler tags, it’s not like it’s a real spoiler, as you knew those first two scenarios were gonna happen, the spoilers would be more of how it happens rather than the fact it happens.
