quiet and seems calm but on the inside his brain is working a thousand miles a minute trying to figure things out. He's not the smarter of the twins, instead of thinking for himself he follows his brother blindly, agreeing with every thing he says and following his every command. He takes the blame for any bad thing Youngmin does without asking any questions or complaining about what he suffers. He finds it hard to trust any one but his brother, and doesn't like it when any one else is talking to Youngmin, he's very protective and possessive.
