Love rat cheated him, but he still felt bad. Will he be punished?

Yes, how did he lose you in the first place, and how did he lose the person he loved later? This is a causal cycle. You don't have to be sad. I'm just like you, but in the end, he didn't lose that woman. The woman is stupid, I don't know. He also blames himself for being too self-righteous, so the girl doesn't have to be sad. Sadness is temporary, and she has not experienced any growth. He was a passer-by and missed it for the sake of passer-by.
