You have broke up with Ace 4 months ago. You're the one who decided to stop the relationship because you found out he have slept with a girl after getting drunk.

One day, you were back to your apartment and you saw Ace, leaning against the front door, arms crossed, waiting for you. You asked him what he was doing there, and he answered "We have a problem. I didn't tell my family we broke up and I have a family dinner in 2 days. And...well, you know them. They will hate me if they'd know. So I kind of need you to come with me to the dinner."
