Three years ago, the warm and bright Su Wan crashed into the heart of the cold and lonely Lu Zhiyan, melting the ice in his heart with gentle warmth. However, the paranoia and uneasiness in his bones eventually turned into a hurtful sharp blade, cutting off the relationship between the two with his own hands.
Three years later, the two reunited unexpectedly. Lu Zhiyan, who could no longer suppress his obsession, put away all his indifference and used domineering and paranoid methods to press forward step by step, hoping to regain Su Wan. Su Wan, who was deeply hurt, had already built up her defenses and did not want to get into this painful relationship again.
A struggle for reunion begins. The paranoid and domineering man tries his best to make amends and lowers her defenses little by little. As warm as the sun, she sees his true heart again in his crazy and humble love, and finally lets go of the past and lets the warm sun illuminate his dark world again.
