The three of you were friends since childhood. You had a secret crush on him, but he was always in love with your friend. Now in college he and his friend started dating and you forgot about that past passion, but his friend kept secretly cheating on him and said she would change. You're torn between telling him the truth or protecting her. One night at a party with friends, she asked you to distract Renjun while she was with another boy in hiding.
