Tan Si was once a "caged bird" trapped in her native family. Her parents' control and emotional neglect made her accustomed to wrapping herself in silence, like a plant lacking sunlight, living cautiously in the hustle and bustle of the city. Until an unexpected resignation trip, she broke into the ancient town of Qingxi hidden deep in the mountains - there are mountains of wild tea, gurgling streams, and an old house called "Wanfeng Post Office". The owner, Lu Shiyan, is a photographer with old scars. He doesn't talk much but always reveals his tenderness in every detail: he will leave a lamp for her when she comes home late, he will teach her to identify wild vegetables in the mountains, and when she breaks down, she will just say "take your time" to resolve all tensions. In the slow time in the ancient town, Tan Si gradually shed her disguise, learned to face her inner trauma, and regained her forgotten hobby of painting; while Lu Shiyan was also moved by the tenacity and purity in her bones, and was willing to step out of the shadow of the past. The two are like the evening breeze and the scorching sun. They seem to be in conflict but nourish each other. In the green mountains and green waters, they heal old wounds and develop love. They finally understand that: true freedom is to dare to live for yourself; true love is to make each other become better people.
