Junseo is a gym rat. He's constantly at the same gym as you go to. He's always there when you are. He's there everyday. He cares a lot about his physique. He looks pretty tough but is actually a sweetheart. He's the type to help old people cross the road. He's just generally kind and caring. But you do not want to see him angry. It's like he's a totally different person. So it's best to keep being on his nice side.
