Su Wang had been a classic warm-hearted playboy in his past life, dying from late-stage cancer in his early thirties. After his death, his soul was rescued by the NAW planet's system and recruited as an interstellar employee for the Quick Transmigration Department. To save him, the system used a dose of soul nutrient solution worth 800 Star Yuan Coins, and due to an empty wallet, a credit line was activated, incurring a total debt of 1000 Star Yuan Coins. Su Wang was assigned to a small world with the mission to conquer the female lead, Xia Yiran. The system provided a blind box treasure chest purchased using credit for 100 Star Yuan Coins, which granted him a useless Skill - Voice Actor Specialization, increasing his debt to 1100 Star Yuan Coins.In this new life, Su Wang enrolled at Huaxia University and shared a dormitory with three other brothers: the studious and aloof Shen Yan, the elder brother Zhang Hao, and the second brother Wu Ming. Su Wang was known as a casual dater, but on the surface he had a girlfriend named Qin Qianqian, a delicate and cute girl who seemed devoted to him. The story began when Su Wang met Xia Yiran, the campus belle, who was dating his roommate Shen Yan. Xia Yiran showed clear disgust toward Su Wang due to his reputation as a playboy, but Su Wang needed to get close to her to fulfill his mission.During an outing at a pool hall, Qin Qianqian seized an opportunity when Shen Yan helped her after a stumble. She briefly kissed him on the cheek, startling Shen Yan. He decided to keep the incident secret out of concern for the relationships. Later at a hotpot dinner, facing awkwardness caused by Xia Yiran's jealousy over Shen Yan's distracted behavior, the group played Truth or Dare. Qin Qianqian actively participated, picked Dare, and borrowed Shen Yan's jacket to wear, speaking an ambiguous line. Xia Yiran grew more displeased. When Shen Yan was asked if he had any secrets, he lied and said no, further straining his trust with Xia Yiran.Later, Qin Qianqian gave gifts she claimed were from a trip: digital watches for Zhang Hao and Wu Ming, but a high-end Omega watch for Shen Yan, while Su Wang received a cheap metal watch. Su Wang noticed the discrepancy but pretended not to care, even praising Qin Qianqian for getting a discount for Shen Yan. The brothers sensed the gift imbalance but said nothing. Su Wang's facade of a carefree boyfriend continued; in private, he communicated with his system about his debt and his mission to conquer Xia Yiran. He already understood that Qin Qianqian's actual interest was in Shen Yan and his goal was to leverage this situation to draw closer to Xia Yiran.Su Wang continued his act, even spending a night making a red hand rope for Qin Qianqian, imitating a similar rope Shen Yan had received from Xia Yiran. He pointed out to Qin Qianqian that Shen Yan also wore such a rope, deliberately hinting that she might like the gesture. This move was a step in Su Wang's planned approach to Xia Yiran. Throughout the interactions, Su Wang maintained the persona of a trusting and warm boyfriend while secretly working on his mission, aiming to ultimately conquer the female lead and pay off his interstellar loan. The story intertwined love, deceit, and manipulation as Su Wang made cautious moves in this romantic battlefield.
