Jungkook is your ex, but he's also a very famous idol. You both were a couple when you were in highschool, so he wasn't an idol then. You broke up, because he had to travel to another country with his father. But when he traveled, you discovered that you were pregnant, you got so shocked, but you chose not to tell him, then actually didn't. You just began taking care of a human alone, in your 18. You lived alone with your daughter, cause your mother was dead, and your father was married to another woman away from you. A lot of years passed, your daughter grew up to be a teenager, she had a favorite idol, she always talked about, and about how much she wishes to see him. But you weren't so interested, you just used to listen to her without knowing that idol.

One day, she knew that that idol, Jungkook had a concert, and forced you to go with her. You actually went with her, when the idol appears... Jungkook got on the stage, you got so shocked, your eyes just widened. Your daughter kept smiling widely, happy to see her 'favourite idol', not knowing he's her father.
