Zhang Yang, a handsome transmigrator with no system and a cynical view on romance, is forcibly signed up for a celebrity dating reality show by his desperate mother. Determined to remain single and focus on his career, he enters the program 'Let's Fall in Love' with the sole intention of sabotaging any potential connections. His blunt, hilariously straight-man responses shock the production team and delight the online audience.

However, his plans take an unexpected turn when he meets his partner, the famous actress Bai Lu. Just as he resigns himself to a month of awkward acting, a 'Love System' finally activates, offering him a choice between becoming a simp or embracing his true, unfiltered self. Naturally, Zhang Yang chooses the latter.

Armed with new skills and a commitment to being authentically difficult, he proceeds to dismantle romantic tropes live on air, inadvertently captivating his co-star and the nation while trying his best to drive everyone, especially Bai Lu, absolutely crazy.
