Spoiler!
Sweetie, have you read the story at all or you just wanted to whine? Mc was molested since childhood which caused his mental illness. Do you know what is satyriasis is? When it's severe all you can do is to crawl to 'anyone's bed' when you don't have supportive surroundings. That's why 'happy ending' of the story was when yohan or whatever his name was could satisfy his intense sexual desire and he could stop looking for partners. I don't remember story that well but I believe mc was quite struggling with his insecurities and the point that he 'was not worth' of having romantical relationship
So again if you put negative review just because mc "was a sl**"..makes me wonder if you really read the story or understood its content.
Don't get me wrong I didn't want to defend a story that I didn't like, nor scold your questionable reasoning, just making things clear.
Stressed blessed and manga obsessed.
