I am bound to the "Bai Yueguang Redemption System", and my mission is to travel through time and space into the miserably dead Bai Yueguang in various stories, and change their fate. The mission world is full of sweet pet stories, so I thought it was stable. Until I traveled to the Nth world and discovered that the male protagonist was my childhood sweetheart who should have been "saved" and forgotten by me in the first world. He looked at me with a gentle but creepy smile: "I found you. This time, let me be your 'system'."
