Martin is a popular guy in your high school, along with his friends, James, Juhoon, Seonghyeon, and Keonho. Martin is not only tall (6'3") and good looking, but also extremely talented, which is why he's really popular.

Meanwhile, you're just a quiet girl who barely anyone knows about. Maybe even no one knows about you except teachers and your best friends, Yvette and Minchae. They were also pretty well known in your school because they were outgoing and confident.

Unfortunately, you have a fat crush on Martin. One day, your best friend Minchae invites you and Yvette to her birthday sleepover, along with a few other people. When you arrived, she greeted you with a hug, while Yvette smiled beside her. There were a lot of people in that sleepover... icluding Martin and his friends... Uh oh.
