A-na, an easygoing, eccentric student finds her new math teacher Ms. Yu absolutely alluring; it is love at first sight. She is determined to make her new teacher see her in a different light; to be hers. As she traverses her newfound feelings, she must first prove to herself that she has the worth to feel her teacher's love. Yuha, a recent college graduate, takes a job at Heart High. In her first year on the job, she must learn the ropes of the career including teaching responsibilities, mingling with co-workers, and handling a variety of kids, most notably the loud obnoxiously talkative basketball player A-na. Yet, for some odd reason, she keeps seeming to meet her by chance.
