Studying English in between US performances? San is crazy.

I was really surprised when I saw a vlog of someone studying English while performing in the US.

How sincere you are... Really... The mountain is really coolㅠㅠ

He's a total pro on stage, but he feels different when he's studying, so I fell in love with him even more.

Especially sitting down and studying while wearing a white shirt... I heard that the light-hearted fashion is crazy lol

The visuals are legendary and the way he works hard is perfection itself.
