I don't like second 2 ( ̄へ ̄)
Story lost consistence, characters became dull and the smut isn't funny anymore.
chulsoo has become a completely jerk. I loved him because I though he was a lovely, kindly, puppy, who was supposed to be protecting his one-sided relationship. And he had eggs to push out other men. Second season's flashbacks turned him into a manipulator bitch. He's the main reason MC can't fall in love again. He couldn't get her so he broke her and pretended to comfort her.
2. I can't believe how fool are those guys anymore. It doesn't make sense to me. They are just smut meat. They also disappear and appear when author wants to. Moreover, they all are becoming more and more alike. Just smut meat. ヽ(`Д´)ノ ヽ(`Д´)ノ

So, now it's time to look forward to season 2ヾ(☆▽☆)

I don't know if there is more to the manga as from what I have seen we are caught up to the raws unless that is we get a season 2/story arc.
When I said there was more than one arc I was referring to the novel there are extras after this but I was mainly talking about the novel which has from what I can tell more than one arc.
Novelupdates.com has the novel which have started on the next volume however, https://ncode.syosetu.com/n2766dz/ this link will take you to the raws.
Which if you read it on google it will self-translate which on the downside means the translation is really poor quality but on the plus side you will be able to read more of the story,also from what I can tell the story appears to be finished.
I don't understand anything(╯°Д °)╯╧╧
