Lan Jie is seven years older than Tiezhu. To help him walk out of the mountain village, she mortgaged her house and pawned her silver bracelet, carrying the debt alone, yet hiding her love in the phrase of treating you like a younger brother. Three months later, Tiezhu returned, running into her being forced into marriage by a bully. Facing debt rumors and cheating framing, he stepped forward to protect her, bravely confessing that it is not repaying gratitude, it is wanting to marry you. One fears delaying, one refuses to retreat, can they cross worldly prejudices, turning the deep affection of a two-way rush into the fireworks of guarding each other for a lifetime.
