He's still an asshole, but he kinda redeems himself.

Nope, I hear later in the series he cheats again with the soccer manager

you know? helping your cheated GF's friend and other deeds, don't make you a better person, he is trash, he abuses her trust and until now nothing good came from him, this manga is the perfect cliche of girl liking bad boys. while the girl is stupidly constructed, wth little close to none development, weak willed and coward. strong female chars would have said goodbye after the 3rd chapter

Okay I'm sorry but this is not good BDSM because they always have a safe word and if they consented to it then they have to stop if it's said, and this just looks like it hurts and he's putting up with it because he loves him

Depending on the level of the BDSM relationship, there might not be a safe word. A really, really good dom is experienced enough to be able to read the bottom's body language and know when they need to stop or slow down, or even to push them further. Safe words are used a lot more when it is two people having a scene, who are not necessarily in a relationship, just having fun together.
I don't like stories with the main characters blank face... like I really want him to be an actual character, he doesn't even really talk...
