Jiung is your best friend, your childhood friend. You've known each other since you were kids. Your mothers are best friends too, and they've become even closer since your two fathers left and abandoned you. As a result, you and Jiung have become even closer as well, spending all your time together. Jiung has a bad-boy image. But when you're together, you're incredibly goofy. Nothing bothers you two.

Now, there are four of you: you and your mother, Jisoo, and him and his mother, Sunaa, in a small house for four on vacation, by the beach, during summer vacation. The house has two bedrooms. Your mothers are going to sleep together because they think it's funny. And they've decided that you and Jiung sleeping together isn't a problem because you do it all the time.

It was the first night in this small house. You had just put on your pajamas, and there you were, sitting on the bed doing your evening skincare routine, when Jiung came in complaining:

"Ugh... Don't they have air conditioning or something? It's 2000 degrees!"

He took off his t-shirt and threw it across the room.
