i dont remember the drama w the grandma someobe fill me in

granny left byuls mom when mom was a kid- basically abandoned him and then later in the story, they reunited but mom was obv mad at granny cause bro got abandoned at a ripe age that's all I rmeber hope this helps

Ok so grandma left hye- sung( the mom)when he was small. She was toxic and abusive.hell she even told the mom that she wished he was never born. So yeah they have a very rough relationship

wtf shes a bitch then. this gonna be a huge thing in the future then

But yk the grandma also has an extremely sad backstory u can read it in (love is an illusion). Idr well but I think she had forced teen pregnancy or smtng (not sure tho)

i read the main story back when it was releasing so i dont remember a single thing lol
