Lin Yi is Gu Yanchen's fiancée, brought into his life through a family-arranged marriage and constantly by his side. She hopes that spending time together will eventually make them fall in love. During the promotion of an intangible cultural heritage project, she witnesses Gu Yanchen, usually distant and cold, repeatedly making exceptions and showing favoritism toward Su Wan, a woman from the mountains. Su Wan even gradually awakens memories of the mountain forest that Gu Yanchen has buried for two years. Lin Yi experiences disappointment and tests the waters, but always maintains her dignity and refuses to get involved in any schemes or conflicts. In the end, realizing that she will never reach Gu Yanchen's heart, she calmly takes the initiative to end their engagement, making a graceful exit and allowing Gu Yanchen and Su Wan to rekindle their romance.
