su doesn't even know how to emotionally be present for himself, he turns to finding ways to either be destructive or just acting out in other ways. partying. drinking/smoking too much. a lot of the image he plays into around people when it's not all him. not sure about su's relationship with his mother just yet, probably stagnant because of his fathers wishes. rapid cycling bipolar, yikes. su would be understanding of it and try to figure out how to navigate around it when he jumps from one to the next in a cycle.
