Yu Sui is a Beta who was bound to a system after dying and gains resurrection energy by completing missions in an alternate world where only men exist. He is assigned to pretend to be an Alpha with 4S mental power, though he lacks any pheromones and is physically weaker than typical Alphas. He deeply hates Alphas due to perceived genetic flaws and vents on a burner account online, calling them arrogant and reckless. In reality, he is sensitive, cowardly, and easily flustered, especially by physical contact. He is extremely beautiful and slender, with a venomous tongue but no real power. His main mission is to help the protagonist Shen Anliu and the corrupted original TYE members, though he often makes things worse. He struggles with the world's gender dynamics and finds it hard to accept male intimacy.
