Do yall think the string being attached to the girl has to do with Kihoon's curse of losing his most precious things? Like she could possibly be the other choice...
@suckmyass I am here to remind you guys few things that- 1.This is BL, 2. The main couple love each other, 3. The red string related to them from their past life. Maybe they died unfortunately without being together, so they got another life to correct there mistakes and be together. Unsuccessful outcome may lead to another reborn until they are actually together!! (I am assuming this.) 4. The girl can be used as a jealousy factor to influence Kihoon to accept his feelings and be in a relationship with his love. 5. The amount of obsession Yeon has for sunbae, I don't think he'll even give 10% to any other relationships.
