I've been not liked Yuki from the beginning. This dude knew he was gay before he married Misaki, but still married her because his weak self couldn't stand up to his father. Then, has a whole other relationship behind his wife's back, but then gets butt-hurt when Misaki and Shuhei share ONE kiss. Like he's a b*tch. However, Misaki needed to hear that, I understand she was trying to make this work, but your can't make something like this work......
Ra-im needs to see a therapist because she obviously has some unresolved mental health issues that she needs to work out, and hopefully soon before she ends up doing something crazy. (Also people, you can't rely on others to bring you happiness!!!)
