Reborn as the Cannon-Fodder Boyfriend of the Protagonist's Love Interest

[Third-person narration] Coming soon: The Adorable Little Zombie Keeps Picking on Bad Men. Blurb at the bottom.

That's right, I transmigrated into the green-hat boyfriend of a romance-novel bottom: a pure-hearted 180-centimeter-tall college student. How do I know? Because I transmigrated into a book.

In the story, my male sweetheart would get tangled up with countless men, serving up a top-tier showdown every day. A possessive, authoritarian CEO, a mature and steady triple-threat actor, a romantic and melancholy painter, and a young, gentle university professor would all fight over him.

And as the boyfriend who got cheated on, I also had a secret...

I'm straight.

*

To get home, I diligently followed the plot and pursued the romance-novel bottom, all the while hoping someone would cheat on me. Then, once my male sweetheart was busy with someone else, I could leave in despair and get written out of the story.

But the romance-novel bottom refused to cooperate. I realized this wouldn't work, so I decided to take action. I stopped the gentle professor on his way home from work, only for the romance-novel bottom to force a kiss on me right there in the street!

The professor didn't even blink. His voice was full of amusement. "Carry on."

I sat alone all night, smoking and tapping my foot. A straight man never gives up!

So I set my sights on the possessive CEO, who was coming to give a talk at our school the following week. That day, while the CEO was earnestly sharing his experience in the classroom, someone was sucking hard on my mouth in a bathroom stall.

"Mmph, you bastard!"

Then I discovered another earth-shattering secret: the romance-novel bottom liked me.

"Honey, come eat!" The boy, dressed in a sailor uniform and wearing cat ears, smiled tenderly at him.

Who could resist a husband who called me honey, was a fantastic cook, and even dressed up in a uniform for me?

PS

1. The love interests are each other's first love. The bottom reads fanfiction.

2. The protagonist is imperfect and has plenty of flaws, but the top spoils him rotten.

3. There will be cross-dressing scenes.

4. The main story is told in third person.

5. A free-spirited, easygoing, straight senior who is easy to coax X a cold, aloof, calculating junior who knows how to draw people in.

Coming soon:

Nan Xing was a cute, sweet, and scatterbrained little zombie. After starving to death, he was bound to a Cannon Fodder System.

"Our mission is to bully him, provoke him, and toy with him! We have to show the protagonist that cannon fodder isn't to be messed with!" the System cried desperately.

The little zombie tilted his head.

"Complete the mission, and you'll get a delicious little cake as a reward."

Nan Xing's eyes lit up. "Yay!"

World One: Jealous that everyone adored his older brother, Nan Xing bullied him every day and offended every prodigy who looked up to him.

Later, those prodigies surrounded Nan Xing and demanded to know which one he'd choose.

But the older brother he'd bullied pulled him into his arms. "Xingxing, why didn't you come bully me today? I've been waiting so long."

World Two: A flamboyant, dissolute young master from a wealthy family hated his illegitimate older brother, so he forcibly claimed the actor his brother liked.

Only after getting the actor into bed did he learn that the other man was also an omega, and that he'd spent the entire night topping Nan Xing.

Nan Xing woke up aching all over and hurriedly fled, planning to have his assistant find someone else to help him recover.

But the man cornered him against a wall. "Baby, who are you going to see? Hmm?"

World Three: Nan Xing was a greedy, washed-up streamer. Even being paired with a big shot who had trillions of fans wasn't enough for him. He used all kinds of dirty tricks to ride the big shot's coattails and make even more money.

The big shot loathed his parasitic behavior, but had to put up with him because their compatibility was as high as 60%.

Then a beautiful merperson appeared, with 99% compatibility with the big shot.

Afraid of being made to pay for his past misdeeds, Nan Xing tried to escape back to the slums.

But the big shot pinned him to the bed. "You got what you wanted from me, and now you're trying to run? What do you take me for?"

Theme: Working hard at life can make it more beautiful.
