Happy 23rd Birthday to Monsta X's dancer and vocalist Hyungwon (Chae Hung Won).
He is the 'pretty boy' of the group and considered one of the visuals. He still does modeling, and I can see why.
Hyungwon has shown us his abs, but I know he's not the one people think of when you mention Monsta X and Abs. He probably looks this good, because the poor boy can't cook.
Happy Birthday Hyungwon.
