@Sam TJ is YWs first (and only) choice. If he isn't, then why hasn't Youngwoo chosen Jo already? Jo lived with him, took care of him, introduced him to his family, and even asked him to leave with him, but what did Youngwoo do? He cheated on Jo with TJ, told TJ he was miserable without him, and asked TJ to give up everything and run away with him. Ian isn't someone who wants to move on but can't. He is someone who only sees a future with the man he's loved for 20+ years. Jo is the obstacle, not TJ. TJ is who Ian wants and needs.
