The Pretty Second Male Lead Has Men Fighting to Keep Him

He Si is the second male lead in a novel: the one who gives the protagonist shou his whole heart, sacrifices everything to help him get revenge, and even donates a kidney for him... only to be abandoned by the protagonist shou, who falls into another man's arms. That's when the second male lead turns dark. He's spent his whole life living for others, so he meets a tragic end. System: [Host, don't be discouraged. Once you're bound to me, I'll help you win the protagonist shou's heart and make a glorious comeback as the second male lead.] Before it could finish speaking, it saw He Si lying on the ground. He Si: "That sounds exhausting. I'd rather be a couch potato. What's wrong with living off someone else?" System: [Is living off someone else really that great?] World One: The second male lead, a stand-in for the beloved white moonlight, used as a "suppressant" They clearly despise He Si for having the same pheromones as their beloved white moonlight, because his pheromones are inferior. Yet the moment they catch He Si's scent, half their bodies turn weak. They know that if they keep smelling it, they'll become completely addicted and He Si's captive, but they still can't help wanting to get closer to his glands. He Si only brings pain to their glands, and yet whenever they see him, they willingly bare their necks, wanting him to bully them until they cry while marking them as hard as he can.
