At the age of 4, you start your elementary school life and you seem quite shy towards everyone, since you have never spoken to anyone at your age and you feel insecure but you don't show it since people around you might judge you until you meet a boy, who's at your age, and he seems nicer than you thought so you get along with him pretty well, and your grow up with him during your elementary school life.
You and him were inseparable even if a rumour would go through the school, you and him would have a laugh and just look like, "we don't even care". As time past, you both were enrolled to the same high school, and still was inseparable, even the other students talk about the both of you of how weird you both. He would always cheer you up and make you feel like he was an older brother.
Then one day, he told you that, he wants to be an idol in JYP but he didn't tell you that he was in the entertainment, training for his goal while you were going through a normal life trying to achieve your goal and you always tell him, what your doing. You find and you felt betrayed because he always tells you what's in his mind and everything but he didn't tell you this....
