met my match

In the Korean comments

One top comment reads, in translation, “Hearts2Hearts is the only group with a comedy member like Stella and even comedian interns like Ye-on and Jiwoo.” It jokingly casts Stella as the group’s established comic and the other two as newcomers to that unofficial role.

What the words mean

개그 담당 (gaegeu damdang, “the member in charge of comedy”) and 개그맨 인턴 (gaegeumaen inteon, “comedian interns”) are playful, exaggerated labels here, not official positions. Another repeated expression, 얼굴합 (eolgulhap, “face combination”), means that the three members’ appearances complement one another especially well; it is casual fandom language about a group’s visual chemistry.
