Lu Yuan goes overseas and entrusts his old family home, filled with precious family memories, to his maternal aunt to look after. But she sees his trust as an opportunity to make money. His aunt's family secretly changes the locks, moves into the house, and rents it out for profit. When Lu Yuan returns to reclaim his property, they twist the facts and refuse to let go, insisting on an agreement as an excuse. Rather than acting impulsively or getting into an argument, Lu Yuan carefully gathers evidence and pursues legal remedies step by step, determined to protect what rightfully belongs to him.
