Pairing: Sungmin/Siwon (Eunhyuk/Sungmin)
Summary: Donghae lets the challenge hang between them for a moment, and when Sungmin doesn’t take it, he adds, “We’ve made a bet, Hyukjae and me. Two hundred thousand won. He thinks your girly act can fool anyone. I don’t think it can.”
Notes: Crossdressing!Sungmin. Counting Backwards, part 3.
