Was the thread connected to the brother but he wanted to cut it so he can sleep with the mc?..
Heewon's thread has not connected to Hangyul's brother it hasn't connected to anyone ever since it was cut by eunhan heewon thinks his soul mate is the brother but their threads were cut so he's telling the shaman to perform the ritual to reconnect it his actual soulmate is Hangyul also yes he's "in love" with the brother so he says but I don't believe his feelings towards Hangyul's brother are real because how are you going to confess to someone and then even think about having an affair with their little brother that just gross :/
Because his little brother likes him! I mean just because you’re soulmates doesn’t mean that someone one won’t like you
That’s what I was thinking! Maybe he knows about his brother’s crush!
