Su Si's entire youth revolved around Gu Yanshen. She gave up studying abroad for him and blocked all the troubles for him. Even when his Bai Yueguang returned to China, she smiled and said "it doesn't matter." But in exchange for her compromise, he asked her to apologize to Bai Yueguang in public, and even withheld her project just to pave the way for Bai Yueguang.
When she desperately signed the resignation letter and disappeared from his world, Gu Yanshen realized that the tenderness and preference that he had ignored had already been engraved in his bones and blood. Late at night when the neon lights were out, he knelt downstairs in her studio with red eyes, humbly begging her to turn back, but he only saw her being protected by another man in his arms, smiling with a strange look on his face.
