behind the red baseball cap; jeongcheol

Jeonghan, a strikingly handsome university student, is juggling his studies, baseball practice, and a complicated love life. One night, he nearly hooks up with a mysterious man who has a gummy smile, unaware that fate has more in store for him. The following week, Jeonghan is shocked to discover that this man-Seungcheol, a national baseball player with a fierce reputation-has been introduced as the university's new coach.

From their first encounter as coach and player, things do not go smoothly. Seungcheol's aloof attitude leaves Jeonghan feeling dismissed, convinced that the older man cares about him only for his athletic potential. The tension between them grows as Seungcheol pushes Jeonghan harder on the field, leading to clashes and frustration, especially as Jeonghan is forced to confront feelings he wishes he could ignore.

Fortunately, Jeonghan has a bright spot in his life-his younger brother, Seungkwan, who brings light and humor to his days. Alongside Seungkwan, Jeonghan's close-knit group of friends supports him, reminding him of his worth, potential, and the importance of letting people in.
