He said he went home early during the MT because his girlfriend had a cold.

I was watching a video of Hong Jin-kyung's family MT, and when the company dinner was in full swing, Grie got up to leave first.

It turned out he went home early because he was worried about his girlfriend catching a cold.

Hong Jin-kyung teased him a lot, asking if he was really leaving just because his girlfriend had a cold, but he looked like a total romantic.
