at the start of freshman year, park chaewon shared a room with jeon heejin and kim hyunjin who were already best friends since high school and they didn't hesitate to let chaewon join their group. although the three of them had different personalities and majors, they have learned to adore and understand each other, almost inseparable when they were all available. they were ready to face the sophomore year headstrong until a particular group date with the athletes from the soccer team of the university, namely hwang hyunjin, na jaemin, and kim seungmin, happened.
