During their graduation trip, Lin Wan was abandoned at a highway service area by Lu Chen, her boyfriend of four years, and his childhood friend Su Yao. For four years, she took care of everything for Lu Chen, yet she was always regarded as a burden. No longer humbly chasing after him, Lin Wan traveled to Linhai alone, joined a cultural tourism studio, crafted slow-travel routes, wrote columns, and won the appreciation of editor-in-chief Zhou Yu. Faced with Lu Chen's attempts to win her back and Su Yao's belated apology, she no longer depended on others, reshaping herself through words. Missing the old mountains and rivers, she finally met her own sea.
