To save her critically ill mother, art student Xu Nian makes a deal with the Memory Pawnshop, becoming the substitute for Su Wei, the white moonlight of chaebol Jiang Cheng. As they spend time together, Xu Nian falls in love, but Jiang Cheng erases her heart-fluttering memories. When Jiang Cheng wakes up to reality, Xu Nian has already pawned her self-awareness and completely forgotten him, sparking a heart-wrenching chasing-wife crematorium trope. In the end, Xu Nian breaks free from her shackles and walks away to start a new life, while Jiang Cheng remains trapped in remorse.
