Anime Crossover: Why Must I Save the World for a Happy Ending?

A young man who'd just finished his college entrance exams hears a truck rumbling down an alley and promptly faints. Is this a case of human nature gone twisted, or morality gone rotten? Tune in to find out... Wait, stop! What the heck is this?!

My name is Kane, and I'm about to start college. That's right, I transmigrated, into a... um... anime crossover world? And I have to live with a silver-haired beauty. Sounds like a wonderful story. But why did this have to happen right after I finished my exams?!

Well, according to the System's mission, all I have to do is help people get their happy endings in this so-called anime crossover world... Then can someone explain what this monster, who's about as powerful as I am, is supposed to be?!

Yeah, send me 50 yuan and I'll tell you how to get home.

(One or two female leads.) (The author came up with this idea while rereading one of the anime crossover novels that got them into the genre. It's just a personal idea, so read on and see how it goes.)
