Changbin completely froze the moment Chan put one knee on the floor, heart almost fluttering out of his chest. It's not something they had talked about before, and even though Chan's joking on the moment, he knows for a fact that this might have a deeper meaning.

L.joe is suffering and he doesn't know why, but he won't allow that to distract him from improving himself and overall improving Teen Top.
