[20230806] FirstKhaotung FM IN Taipei - 殘酷二選一，只是想想，兩人就哭到不行 

Essentially they were both asked "If you had to choose between A) Forgetting the other person or B) The other person can't remember you?" First answered B because it means the other person can happily move on without any memories of you, so you carry the pain of remembering them alone. Khaotung answered B as well, because he'd rather First forgets him but he wants to remember all they experienced together (both the good and the bad).
