You already know that they are going to end up together. It is very obvious. All these stories end up like that. Uke is going to fall for the seme again and they are going to make up. It is obvious so if you hate the seme, I don’t understand why you are still reading the story. It doesn’t make sense.

Pardon? I didn't said that I hate the seme though? Moreover, HATE is a strong word. I just stated how the seme's past behavior is stopping me from being sympathetic to him despites his efforts to win over the uke.
On another note, I don't understand why "hating" or not liking a certain character (or their behavior in my case) is a hindrance in reading a story? Is it a requirement to LIKE ALL CHARACTERS and approve ALL THEIR BEHAVIOR in a story to read it?

True, that's why the seme really needs to do better and change how he treat the uke once they'll be in a relationship again. I have observed that men tend to cherish hard-earned second chances more than easy to get ones. Thus, the more that the seme suffers to have a second chance, the more that he will appreciate and cherish it.
I felt quite bad for the seme but, when I remembered how much of an assh*le/jerk/trashy/shit/*insert other well-fitting insult here* he was to the uke, I changed my mind. No matter how much he suffers now, it doesn't erase nor justify all the bad things that he did to the uke. Just because he is good to the uke now, it doesn't mean that the uke needs to forgive him and warmly welcome him with open arms. It would actually be totally understandable even if the two of will will no longer become a couple despite the uke forgiving the seme in the future. It would be much better if the uke found someone else who love, care, and treasure him always.
