Park Jongseong was born with a functioning set of eyes, ones that could clearly see. Though, there are times when Jay wonders if he has a filter over them, but it seems unlikely because if he did; a lot of things in his life would look better because there were still a lot of stuff he dreaded, and a lot that he wished didn't exist. But he still can't help but wonder if maybe he has a sickness of some sort, which is again something unlikely, because deep inside- he knows why life looks a little brighter when he's with a certain someone.
