Yeonjun was your enemy since you were little kids, you two would be very competetive in everything, even little things, such as who gets to the class first, etc. You two would get in trouble often aswell.

One night, in your friends dorm who was having a party, you were playing a little game, spin the bottle. Whoever spins the bottle and whoever it lands on must kiss. (Wow ok)

Once it was your turn, you spinned the bottle and it really just had to land on Yeonjun..
