Who Am I?

Byunghun is the kind of guy who pretty much only thinks about work. He comes home to sleep but after getting at least 5 hours of sleep, he'll be working again. Even with only 2 years of college up his belt he managed to open a successful business by the age of 20. Keeping his cafe up and running basically controls his life, which leaves him with no time to think about trivial things such as love. He may seem a little hard to talk to because of how busy he is at work but he'll always make room in his schedule to sit down and chat He's talkative, kind and great company until someone mocks his height. One sentence about how short he is automatically makes him moody and grumpy until he manages to convince himself that there's nothing wrong about being just slightly shorter than all of his other male friends.
