Blue Love Between Life and Death Sean said that she would be a tree in her next life. In which episode?

Professor Yin's own daughter loves to live very hard in this single-parent family. When she learned that she was originally a rich girl, she decided to leave 14, the single mother who raised herself, and take refuge in the rich Professor Yin family. However, because she was jealous of Sean, she tried her best to make Sean live a miserable life before, and Sean knew that he was going back to his biological mother, so she had to watch her favorite adoptive parents and younger brother immigrate to the United States.
