Season 1

Ko Gun returns to the illegal gambling spot to make a few more bucks. However, he gets caught up in a bad hand and returns home with cuts and bruises. Meanwhile, as Se Young helps a drunk man home, she runs into Ko Gun at the drunk man's door.

Se Young can't get enough of Gun, and she follows him everywhere, even to his part-time job at the convenience store. Gun takes her to Ji Chul's bar, and she learns about the upcoming Hold'em tournament. Meanwhile, Gun's sister's health deteriorates, forcing Gun to find a means to save her.

Gun stands before the court for illegal gambling. With the help of petitions from his schoolmates, the court sentences him to 100 hours of community service, and he promises not to get involved in illegal gambling activities. Meanwhile, Gun continues to push Se Young away when he returns to school.

Gun is fueled by a heartfelt determination to clinch victory in the 2022 KPL championship, yet his performance in the final game appears unpromising. Despite feeling trapped with unfavorable circumstances stacked against him, he remains resolute, driven by his deep love and dedication to Jun Hee, his father, and Se Young. Although the odds seem insurmountable, he refuses to concede defeat until the very end.
