Can you tell me something about Mako?

He's an unfaithful jerk who cheats on his girlfriend and snaps at Korra.

He's that guy....He's a pro-bending player
boyfriend of Asami Sato and Korra has a crush on him...
He's kinda arrogant....and yeah! he has a brother named Bolin..he's parents has died from firebender when he was only 7 years old and he's older than Bolin...THAT'S ALL WE KNOW SO FAR...

korra has a crush on him but he did not
i could not love him but now i feel he is cheating on asami and if that happened i would love him so much

He's a cool mofo =)
