Sakura1875's manga / #MC is an idiot for forgiving everything he had to her(1)

Started, but dropped. I try reading it again, but once again, I couldn’t help but regret reading it and giving it a second chance. The ML is plain ass a a-hole. The MC is really an idiot, crazy and coocoo for forgiving him even after all he did to her. Like just why, just why?? After a long time, came back to see how it ended to see this sh*t. I gave up on this one. No point trying to reason with it.
