Hahaha, so this is the episode where Mir and his mom were guests and I think they(Shinhwa) was trying to guess the name of Mir’s sister (which is Go EunAh) and Hyesung suddenly answers “MBLAQ’s Cheondung” and they all yell at him that they were talking about Mir and not Thunder XD
“What?! What Thunder?!”
Hyesung: “Isn’t Thunder noona Sandara Park?!”
lmao and at the end, the two guys had speech bubbles that said “Are you an idiot?”
