kaeya's left butt cheek's feed

and not,,, in a good way? i have my own theory. jitae and jian is half brothers. seeing jian's similar hair to their mum i'd assume jitae is the adopted one. they are in a heated feud bcs of who will get their grandpa's company(?) and then there's hajoon, the name that's somehow important to mi eum while the character isn't really that stood up.
