Never liked that manipulative jerk Jamin; felt sorry for Soohyun, he has his flaws but he was sincere, was mad at Daon for how can a smart guy be so stupid, but it all comes to an end and besides Jamin, everyone is moving on, that's needed as part of a healing process.
Only if Jamin could put down his pride and was truthful from the start, things could have been very different for all of them.
