After her death, something claiming to be a system approached her. If she bound herself to it and followed it to various small worlds to complete the task of matchmaking the male and female leads, she could be reborn and gain a healthy body. Yu Nuobai agreed. But every time, she would be pulled into the male lead's arms and kept by his side, and the male lead would even say he loved her!! World One: The obsessive CEO caressed her cheek, his voice low and devilish, "Baby, you smell so good, look at me!" World Two: The sickly emperor gripped her slender waist, his gaze intensely predatory, as if he wanted to devour her whole, "I will take you from me!" World Three: The mermaid prince's large tail clung tightly to his little human, his sharp teeth gently biting her earlobe, his heavenly voice filled with obsession, "You are mine!" World Four: The bandit's rough hands stroked her ankles, picking up a chain to fasten it, his voice fierce, "Don't even think about escaping!" World Five: The rough man stared at her with red eyes, pleading, "Say you love me, and I'll give you my life!" ... Yu Nuobai was completely dumbfounded. She was the female supporting character! Why was the male lead saying he loved her and offering his life? She, the female supporting character, wasn't the one who should be with the male lead! (World order is uncertain)
