Tbh yeah ido did really bad in their past life I would've left the story if it ended on that and I do didn't even felt anything and just moved on but what matters is that he realised what he did wrong and tried to make it better sure it wasn't the best but still he asked for forgiveness and became a green flag from a red flag that's what's matters if I was Sejin I think I would've done the same I guess
