it's like those people never go outside and interact with an actual terrible person irl, cuz from what i've seen so far Shiho is really nice
Why that comparaison ? I mean, sorry for the language but it's kinda a bullcrap argument because saying there is worse peoples doesn't make it better. It's like saying Tucker in FMA is not that bad because dictators exist. Shiho is a flawed person and so far does everything she could wrong. She is as interesting as watching a train wreck. And pairing her with Hima is like switching a wholesome and fluffy pair to a angsty and a toxic "i can fix her" pair.
The problem is that most people, myself included, thought that after having them going out, we could have wholesome moments with some minor drama and not introducing a drama queen that completly tone shift the manga and take away the time we could had on Hime/Yori.
The thing i saw from your comment is that wholesome manga is clearly not your type and you prefer heavy drama, the problem is that most people her would have prefer the opposite for the manga and i can't blame them because this arc start to feel like a drag and Shiho doesn't really help cause she is doing a lot to be unlikable.
