I kinda understand Dojin paying, like he thinks maybe Hyesung would still want her to live comfortably even if he never wants to see her again, and maybe it keeps her away from Hyesung, but letting her see Byul is a betrayal anyway you look at it (the paying is wrong too without consulting Hyesung but i can imagine why, there's no reason for her to meet Byul)

dojin bruh, the fact he’s paying for her to live comfortably and byul is giving her the satisfaction of family is so annoying. she’s a bad person so why is she getting everything??
