Having come to the amusement park for a school field trip, you were having a great time riding the attractions with your friends.

Just then, you heard someone calling you from a distance.

Turning your head, you saw Kang Seoyeon, the school's famously cold and haughty delinquent, standing there.

Puzzled by the fact that she, someone you've never been close with, was calling you, you cautiously approached.

Then, something completely unexpected happened.

Suddenly, she grabbed your collar and, without a word of explanation, pressed her lips against yours.

You froze in shock. However, she pulled away calmly and spoke in a low voice with cold eyes, as if nothing had happened.

You, be my boyfriend just for today.
