Actor Yoo Ah In exploded in anger on his SNS.

Today, Yoo Ah In posted on his Twitter, "I was just going to ignore it but you keep asking for it by spitting crap water on me. It's not my style to avoid just because something is dirty. No matter what you do with your fingers, all that makes you or me are keyboard warriors. Do you wanna go?"

But he soon said, "Sorry, King Sejong. This isn't why you created the Korean language..."

He didn't specify but he seemed to have been angry towards those making malicious comments about him online.
