1. Seung could have been more honest with his feelings instead of lying, but I think he's got a bit of an inferiority complex or whatever. Yeah, him going to Mujin for comfort could have been the worst decision and he knew about Mujin's feelings for him and knew that he wouldn't reject him. 2. Dogyeom had always slept around, which I can see contributed to Seung's indecisiveness. 3. Mujin is a love brained fool, he knew Seung didn't come to him out of love and he also could have seen this not going well, but he still let his unrequainted love for Seung win over his rational thoughts.
