Season 1 of Nha Harn The Series premiered on February 20, 2022.

In the rural village of Non Hin Hae, Yupin and her friends Calcium, Tlemai, Peckey, and Hoykey are middling students who love nothing more than to dance 'na han' in front of the stage at morlam concerts. Things get complicated when Yupin's dancing rivalry with the principal's daughter Yoyay gets her entangled with Sawan—Yoyay's boyfriend and the school's model student—just as she meets Singto, a struggling would-be musician who might well be the man of her dreams. Meanwhile, Tlemai—already under pressure from his strict mother's high expectations for a successful and manly son—fails the grade and finds himself in the same class as K, his pretend girlfriend Calcium's younger brother.
