In one video clip from The Show I think it was Jun K & Taecyeon being interviewed. Jun K says something like "It's difficult if a guy is perfect, it will be a burden to the other party, so the guy has to show some gap" then he tells Taecyeon to show his gap, and he opens Taecyeon's shirt to show Taecyeon's well-built chest, in jest. He repeats this before they close the brief interview. Watch the video clip for The Show with Eng subs.
