After today's kkeomchiz episode Taesan bottom truthers look like fools, this guy is bold enough to turn himself into playboy and make Sungho shy af, he's the #1 switch among Boynextdoor and definitely can BOTH. He's so pretty, I actually prefer him being bottom in fanfics, but Taesan-top fics are always a better read, because it's really hard for authors with 2-3 poor yaoi clichés in their heads to portray such mischievous, stubborn and strong-willed person like him as believable bottom without mis-characterization.
