*You and Jimin have been together for a few years
One day you and Jimin were talking on the phone and Jimin was about to end the call when he heard you to call out to someone on the other side. You forgot to end the call before you starting talking again. "Y/N didn't tell me anyone was at her house" Jimin thought. He heard a mans voice and he became really confused. Even though he knew it's wrong to eavesdrop he still did. "Who were you talking to?" The mans voice said.
Y/N: Oh that was just Jimin. It's good you came just after we finished talking otherwise he would have heard you and start asking questions.
Jimin's eyes widened. "Is she cheating on me?"He thought. His question was imminently answered.
Mans voice: Are you really only seeing him for his money?
Y/N: Yes baby nothing else
Voice: When are you going to break up with him?Jimin didn't want to hear your reply and ended the call. He felt angry and stupid. Angry because whole time you had been using him and stupid because he didn't notice sooner.
Jimin asked to meet up with you the next day and you came.
JM: I need to talk to you about something.Y/N: What would that be? *you smiled sweetly
JM: Who was that man that was at your house yesterday?
You froze.
Y/N: That.. was my cousin
JM: Liar. Do you think I can't recognise the voice of my best friend in high school.
Y/N: Jimin I... you misunderstood
JM: No I think I didn't. I heard your conversation with him when you left the phone on.
Y/N: Jimin it's a misunderstanding! I only love you!
