Didn't his backstory already told? He was a child from unfavorable son. His granny took him in despite hating his mom/dad (i forgot). She looked down on him. The red hair is the cousin (probably granny likes his parents).. jiwoon 1st crush is suha because suha always trying to talk to him when he was a kid but suha thought jiwoon acting like that because he was hated by him. They treated him unfairly. Suha knew granny didn't like jiwoon so much as his effort always got criticized. Thats why he was overly possessive towards suha because he loved him since a very long.
Sorry my english sucks. (づ￣ ³￣)づ
Oh, thanks for the summary.
I meant like WHY does the granny hate himor his parents so much and why is he just takin all this..toxicity?
