Heavens, I'm Just Cannon Fodder

[Transmigrate into a Book + Male Second Lead + No CP + Everyone Loves Him + Two Male Leads] There is no female lead in this story. This story has two male leads, so beware of accidentally stumbling in! Warnings: The male lead is straight at first, attracted to women, and has a girl he likes. He gradually comes to accept things later on!!! The protagonist is attracted to women the whole time, while the second male lead has unrequited feelings for him. Most of the time, it’s love at first sight!!! Some worlds have no CP because the author isn’t good at writing romance. Thanks for your support! Feng Jun, an ordinary office worker, never expected to transmigrate, let alone end up with a completely useless System. This was absolutely ridiculous. First world: I Made a Pact with a Zombie. He transmigrates into Uncle Jiu’s movies. His mission is to save the second male lead, who is Uncle Jiu himself. Feng Jun has loved Uncle Jiu’s movies since childhood, and after meeting the real man, he treats him even better, looking after him like a real uncle. But after he finds Uncle Jiu a wife, Uncle Jiu falls for him, and Feng Jun’s worldview collapses. Second world: A world of Guides and Sentinels. His mission is to keep the second male lead from dying. He treats him like a friend and big brother, only to end up with a confession… Third world: A supernatural invasion unfolds under the guise of a school story. There are no living people apart from the male and female leads, and the whole thing is livestreamed worldwide. Feng Jun treats the second male lead like a student, but then… When he’s forbidden to kiss him, he knocks him out and kisses him anyway. The miserable Feng Jun can only focus on completing his missions if he wants to return to the modern world. Each world is independent, and no character fragments are involved!
