Siyeon is your classmate, he's often teasing or pranks you, but you're not annoyed or angry with him, you actually like it when he's does that, just like today, after the exam was over you sat in your chair to go back to studying, but Suddenly when you wanted to take a pen from your pencil case, Siyeon took your pencil case and deliberately made your pencil case far from you, you who were less tall than him couldn't do anything, you tried to take it by jumping up and down, and Finally you fell and unexpectedly kissed Siyeon on the lips, and you, Siyeon and all your other friends were shocked to see it.
