In an accident, Shen Yixuan lost his memory. He forgot about the actor Lu Jingxing who was with him, and also forgot about all the tender past between the two. He treated Lu Jingxing like a stranger, with prejudice and resistance, and his hurtful words and deeds kept coming, pushing Lu Jingxing to the edge of letting go. When the memory came back and the heart-wrenching regret swept over him, Shen Yixuan suddenly woke up and embarked on a long journey to pursue his husband. He tried his best to make up for the past and win back the person he had let down.
