while attempting to get rid of his own feelings before they ruin his life, Max realizes his friends aren't that loyal and some things you can't tell anyone. Meanwhile, David searches for a kind way to let him down

But Junhoe and Jiwon would always be bad at emotions, and it would be no surprise to Jinhwan if it took a good few years for them to properly confess.
Which is exactly what happened.
Jinhwan really didn't know how he hadn't given up on them yet.
