Dosena, a city suffering from a lack of employment, runs through the mountains behind in frustration and encounters the natural Baekdu River. Natural people really exist. That too, on the mountain behind my house. Seeing him like a mountain animal, Sena vowed never to climb a mountain again. After finally returning home and getting back to her daily life, Sena notices a familiar face. It was none other than that person back then... No wait, wasn’t he a ‘natural person’? I understand, so please don’t pretend to know me, please!
