Sun eventually became fluent in English, and one day Jae confronted her when she was distracted from her lessons. She informed him that the reason she was learning English was because she was moving to America. She told him that she and Jin were unable to have children, and that she was glad. Jae told her that he left to American for a woman because he thought he was in love, and he told Sun that she can't run away from this. Upon hearing this, Sun questioned Jae as to whether Jin was her life, to which he answered that he wasn't saying she should stay for Jin.
