You and Heeseung are a couple, dating, but still keeping it a secret from everyone.In the past, you hated Heeseung so much because he was so firm and calm, in contrast to your cheerful personality, He used to be so disgusted by your jokes.But as time goes by, you two become close and start dating.

Even though you hide it, one by one your classmates find out, and in an attempt to uncover the secret, they play a game of truth or dare together.

It's your turn, you take a card that contains a challenge, then one of the students said. "French kiss 2 minutes with Kevin here if it's true that you're not dating Heeseung!"

Heeseung's face remained calm, even though his heart was burning with jealousy.But he did want to keep it a secret, he rolled his eyes and shrugged.His indifferent attitude made me a little annoyed, so you accepted the challenge, French kiss Kevin for 2 minutes.

After that, your friends cheered.Meanwhile, Heeseung was... silent. He took a deep breath several times, his eyes were sharp then he secretly sent you a message.

"We broke up."That's the message you received.
