Follows Yun Bom, who, after enduring emotional turmoil in Seoul, moves to the small town of Sinsu to begin anew as an exchange teacher. Initially detached and cold toward everything, she gradually opens her heart after meeting Seon Jae Gyu. Seon Jae Gyu is a key figure who stirs up the village with his outrageous antics. He is also the CEO of JK Power Energy and the uncle of Seon Han Gyeol, a student at Sinsu High. Despite his large build and rough first impression reminiscent of a back-alley tough guy, Jae Gyu is someone full of unexpected charm, unwavering devotion, and a deep consideration for others.
