Can the Protagonist of an Explicit Novel Be a Cannon Fodder? [Quick Transmigration]

[Beautiful, flirtatious heartthrob bottom x various tops] The bottom is the protagonist of an explicit novel. He's incredibly handsome, but his mind is full of things that can't be said aloud. After binding himself to a System, he has to travel to different worlds and play the pitiful or detestable cannon fodder characters. Bad news: He can't break character. Good news: It doesn't count if the other person makes the first move. The beautiful young man's hair was dripping wet, clinging to the pale nape of his neck. His eyes were lowered, and he seemed completely unaware of the gazes fixed on him. The tops watched him, nearly going mad. Unable to restrain their sick, twisted feelings, they threatened and tempted him, took him by force, and held him down so he couldn't escape. The bottom whimpered and said no, only to be ruthlessly bullied... or deliberately provoked the top and was harshly punished. [An Extra at an Elite Boys' School] A poor top student, timid and pitiful, who can only meekly agree when threatened by the F4. [Beta Husband] A beta husband deeply in love with his omega wife, who one day gets ravaged by the top Alphas he sees as rivals. [Adoptive Father] The monsters he raised by hand as if they were his own children... [Ancient Times] A crown prince's study companion: How did he end up being dragged onto the bed? [Junior Disciple] That annoying junior disciple: When did he sneak into his master's room? Tentative list The only things that are certain: the bottom is a heartthrob, beautiful and flirtatious, and only wants things that can't be said aloud. There are lots of tops in every world, and they're all virgins. Theme: Anything is possible
