Whoever wondering who the girl is? She is jiwoon's sister. He has two younger twin sibilings that he didn't even know exist until he met his parents. Same with the twin. That disgusting parents never mention about jiwoon to those twin.
P.S: when the parents happily building a family, Jiwoon was suffering in that shitty household under tremendous pressure. This just shows how disgusting and ignorant his parents are. I really don't want him to associate with them ever again. I think last two chapters from the main story showed the reunion with his parents. You guys can read it.
