fr good for him for taking accountability and assuring mc that it was never his fault but honestly i still hope mc to at least reject him even a little bit. I think they both should take their time to understand both their situation and how they honestly feel about each other and not just get swept away by the moment especially since mc still has a lot on his mind and he pretty much need to sort those out more

Honestly I am really impressed Jaemin was able to come to a place where he was able to say all that. At least he is trying to own up to his past behavior.
