when you were a kid, you had a car accident with your parents, luckily you survived but.. your parents didn't. You were sent to an orphanage, there were a lot of kids there, and you noticed that the orphanage is really strict with rules, you got to obey them, you have to behave and you got to hand your belongings to them. While you were there, it wasn't a good experience. No one wanted to adopt you, it makes you sad that, every once in a while when someone gets adopted, you wished it was you. But besides all that you also have an enemy, at least that's what you think. He hates you but you didn't know that he also cares for you.

fast forward, you're now 16, so is your enemy. One day the head Master of the orphanage called you and heeseung in the room where parents sign the papers to adopt someone, so of course you're excited. When you got there you were greeted by two sweet people, your future parents if they adopted you. After all the talking and agreements, the two people signed the papers and both you and heeseung got adopted.

present time, you both are now in college, both of you still hates each other but it seems like he hated you more now.
