Sunghoon is your ex. You two have a dog name Gaeul. but Gaeul is at his daddy's house right now, Sunghoon.

Gaeul is really living with you, but the thought right now Sunghoon having Gaeul tonight in his place is annoying you and can’t let you sleep.

It’s in the midnight when your phone ringing, you wake up and pick it up without checking who it is. but the voice is very familiar.

Sunghoon: “Hey cutie, Gaeul said you should come over and give me my kisses.”

You know he’s trying to get back with you.
