Next is…CHIBA💪 #BOYNEXTDOOR

In the Korean comments

Several comments cast Jaehyun as the eager talker and Sungho as the indulgent listener. One reads, in translation, “It’s exactly like a puppy pestering a cat to play,” while another compares them to “a bubbly girlfriend and a quiet boyfriend who listens to everything.”

What the words mean

치대다 (chidaeda, to cling to or pester) can describe pressing or rubbing up against someone. In the puppy-and-cat comparison here, it playfully means persistently nudging someone for attention or play; the register is casual and affectionate.
