If it someone who put a "Binding sword" curse on Jin, the name is "Kiddard Hall" Jin was in disguise under the surname of "Hister"—Chapter 100
I don't know the chapter but it's when he confronts his older sister's nanny, she was the one that cursed him and she ends up dying because of his older brother's medling, the older sister was really sad
I saw somewhere that he confronts the one who cursed him but I can't find it. Anyone who know what chapter it might be? I feel like I'm going insane
