Su Rongrong: "The biggest mistake I have ever made in my life is to take advantage of you. You are not anyone's pawn, and you should not be our tool. Since I can make you forget once, it doesn't matter the second or third time. Don't blame me for not respecting your wishes. This time, it will be absolutely foolproof."
