His brother? Meaning Hangyum’s twin?
Or did you mean her brother? Meaning Hajin?
Either way, in my opinion the answer is no..... but this story does takes twists.
I think Reyka meant her brother as in hajin like if jahee and that girl breaks up it gives jahee a chance to be with hajin （￣へ￣）
I was think that is what Reyka meant but some people has wanted Hanwool and Jaehee to be a couple. I don’t know how this is going to go but from what is there with the story I wouldn’t think so. Though it is a possibility
I really want his sister to expose that rat but the only thing she is gonna get its to throw his brother to Jaehees arms.
