Wang Qingyue, 28 years old, is a former elite of a garden design institute. Tired of the hypocritical aesthetics of the urban concrete forest, he returned to his hometown of Yunqi Mountain and became a "maintenance worker by removing weeds from the stone steps of the mountain forest." This ancient and niche type of work requires him to neither allow weeds to grow wildly on the stone steps of a thousand-year-old road, covering the road and causing safety hazards, nor to shave off the grass and destroy the original mountain environment. Every time he cuts the knife, he must exercise the utmost care in "proportion".
In the mountains, he met ranger Chen Yu, a man who also had an obsession with the mountain. The two met due to a post-monsoon weed regrowth crisis, and quickly fell in love among the morning mist and stone steps. Chen Yu loves the wild freedom of the mountain, but Wang Qingyue is obsessed with the orderly aesthetics of domesticated vegetation. The initial complementarity gradually evolved into a stubbornness that refused to give in due to the collision between a different place (Chen Yu was transferred to a protected area next door) and professional concepts. The monsoons come and go, the weeds grow again, and their love is also consumed by the distance between reality and ideals in the endless "cleaning" and "crazy growth".
