On a rainy night in London, design graduate Su Wanxing accidentally broke into a private reception to avoid the rain. A warm light and shadow illustration accidentally broke into the long-lost childhood memories of multinational president Lu Zhiyan.
He is a decisive iceberg boss in the business world. The loneliness of being fostered abroad in his childhood made him have a paranoid obsession with "warm light". However, the moment he picked up the painting, the halo in the painting awakened the long-lost throbbing; she is a sober and tenacious dream-chasing illustrator, working hard to pay for her grandmother's surgery, but due to an accidental intrusion, she was forcibly bound by him with "exclusive cooperation".
"From today on, your paintings are only allowed to be shown to me." He surrounded her with overbearing terms, but secretly added medical subsidies to the contract, organized a studio with the best lighting for her, and said loudly when she was being made trouble, "My people are not allowed to touch."
The cold-toned rain alley interweaves with the warm-toned light and shadow, and the secret of the retro pocket watch is gradually revealed - it turns out that the bond between the two was destined as early as their childhood home. His strength is a disguise for lack of love, and her tenacity is a good medicine for healing. From contract binding to two-way sinking, from family resistance to fighting side by side, they understand their true feelings through the tug and save each other in the light and shadow.
This is an obsession that spans time, and it is also a sweet love that is "only gentle to you". When the iceberg boss transforms into a loyal dog, and when the dream-chasing girl shines, all regrets and traumas will eventually be illuminated by each other's warmth.
