Optimistic-Prediction: director and Yoon continue this relationship, slowly start to have feelings. Taesung realizes that his bf did something/acts shady/is toxic, decides to end it bc their relationship was based on a lie or something, or he realizes he doesn’t really love him. Regrets that he pushed Yoon away, tries to get back with him. Yoon is falling for director, wants to move on now, rejects Taesung, starts dating director seriously. Taesung and Yoon now platonic friends. Taesung eventually find someone he really loves after slowly looking and falling for them. He deserves a good relationship even if he can’t be with Yoon, I think he jumped into his current one for the wrong reasons or at a bad time. He’s really only staying because he ‘should’, it seems, even if he does care for his bf. I think, if it’s not Yoon, he should take his time healing, get to know someone else slowly and gradually, fall in love, date, happily ever after
