In her past life, Xiao An'an wrongly gave her heart to Shen Xiuning, willingly acting as the shadow of the white moonlight in his heart, and ultimately ended up in a miserable state after being abandoned. Reborn overnight, she returns to the very last night of their broken relationship. This time she refuses to divorce, acting spoiled and clinging on to warm his heart. Until she witnesses him and the white moonlight smiling at each other on a variety show, she completely loses hope, packs her bags, and plans to leave quietly. But the door is pushed open forcefully, and he pulls her into his arms with red eyes: "You've entered my door, don't even think about leaving in this lifetime."
