Lin Yi, a 24-year-old young programmer, lives in a single-family house with a small courtyard to save money. The landlord is Lin Ruoxi, a mature beauty who is nine years older than him, divorced and has a daughter. Silk nightgown, bare feet looking back, hot porridge late at night, an accidental encounter allowed the well-behaved young man to break into the tender heart of a man who had lived alone for five years.
Under the same roof, ambiguity arises - she teases and tests, he blushes and his heart beats; she is lonely and fragile, but he protects her silently. At the same time, his timid colleague Lin Wanwan, who has a crush on him, his powerful female boss Wen Yining, and the ignorant landlady's daughter Su Wan all break into his life one after another. Four love affairs are intertwined, and a gentle whirlpool quietly takes shape.
From being bullied in the workplace to standing up and fighting back, from being ignorant and passive to being determined and responsible, Lin Yi saw her true heart clearly as she grew up; from not daring to love again to falling bravely, from being cautious to being desperate, Lin Ruoxi found the light that belonged to her while waiting. Faced with the age gap, single parent status, parental opposition, and the attention of others, they withstood all rumors and tests and firmly chose each other.
An encounter that began with a rental contract, a love that spanned a nine-year age difference, from heart-to-heart to staying together, from tenants to family members, it turns out that the right person will always meet unexpectedly at the right time.
