Lin Nian has been in love with Gu Chen for seven years. From their first meeting in the university club to silently accompanying him when she entered his company after graduation, she made her secret love a habit. However, Gu Chen always regarded her as a dispensable "good partner", enjoying the plans she put together overtime and the stomach medicine she handed over when he was sick, but he turned around and treated his partner's daughter with tenderness at the wine party.
Until Lin Nian's father suddenly became seriously ill and needed a huge amount of money for surgery. With red eyes, she asked Gu Chen to advance her salary, but what she got was "the company has procedures." Watching Gu Chen turn around and buy a limited edition bag for his new girlfriend, Lin Nian finally became disheartened. She quit her job, sold all her belongings, and stayed with him day and night in the hospital corridors.
Three years later, Gu Chen, already an industry leader, met Lin Nian again at the bidding meeting. She lost her youthfulness and calmly handled the new company, but there was no warmth in her eyes. Gu Chen began to frantically search for her traces, only to discover the photos of her curled up in the rental house eating cold steamed buns, and the medical records of her running around in the rain to save money and causing a high fever. The sincerity that he once trampled on has now become a thorn in his heart. When he put down his body and asked for reconciliation, Lin Nian just smiled and shook his head: "Mr. Gu, I missed something and it's too late to say sorry."
