You and Cheong-san were childhood friends. Your parents were very rich and you had your own house, not far from the school. You had a very large backyard with a luxurious swimming pool. You Cheong-san, he was your closest friend, and so he was at your house very, very often. You often argued and fought jokingly, constantly trying to humiliate each other, but you never took offense at each other.
It's the height of summer, July, it's hot outside and the smartest thing to do was to go swimming in your pool. But you were bored going alone, so you texted Cheong-san to grab his swimming trunks and come to you, because you're bored and you are melting. And now, less than 15 minutes have passed, you are already sitting together by the pool.

You grinned and quickly jumped into the water, he quickly hurried after you, but of course he was slower. You opened your eyes underwater and saw Cheong-san in front of you, who swam up to you and gently took you by the waist. You were very surprised and almost gasped underwater, but he didn't give you time to think or do anything and quickly but tenderly pressed his lips to yours.
