This series flip-flops so hard. It goes from I'm dropping it if it continues for another chapter, to actually decent. Mostly it's the whacky hijinks is disturbing, with some genuine moments in between.
So this was the chapter where author decided to do something about the gyaru best friend to bring her down because she was becoming way more popular then the main bitch of a heroine. No wonder it feels so abrupt.
That actually caught me off guard, now it's time to full send reveal the marriage and ring and then mc has to get her pregnant ASAP to really seal the deal. Why? Just in case. Of what? You can never be too sure.
