No wonder the (ex) fiance isn't the ml, he actually apologized and listed out what he did wrong and said "I'm sorry". He said "I'm sorry", did I stumble into a different genre? You won't ever (or very rarely) find ml's saying "I'm sorry" and properly addressing their wrongs to the fl. He's also respecting the fl's decision to break things off, even though in this ch (27) he wanted to reverse that decision. He's also still willing to help the fl even though he knows their engagement will be moot later on.
