When students are reassigned to classes in their second year at a key city high school, Su Zhiyu, sensitive and reserved, always eager to please, becomes deskmates with Lu Shiyan, a lonely, broken top student who is quiet and cold. Both are trapped in cold homes and swallow their grievances and emptiness alone. Through their wordless companionship, day after day, she melts the frost surrounding him with her warmth, while he heals her long-standing self-doubt with a love reserved for her alone. There are no melodramatic entanglements, only small, tender acts of support. A deeply healing story of mutual salvation, with a score of 9, and a faint trace of youthful regret, slowly unfolds in the evening breeze of a summer in a small town!
