When a Villainess System Binds to a Male-Oriented Protagonist [Quick Transmigration]

As a villainess-reversal System, it regrets this now. It really regrets it. Where was the pretty girl Host it was promised? How did it accidentally bind itself to the wrong person with one slip of its hand?

And it can't even return him...

The Host the System bound by mistake, Xun Nan, puts on a mocking grin. "Let's get this straight. I'm straight. I only like pretty girls with big breasts and slim waists."

["Um, don't worry, Host. Your mission secret identity will definitely be a pretty girl with big breasts and a slim waist..."]

"...Don't say I didn't warn you."

[I already regret it...] The System falls silent.

Apocalyptic supernatural-ability world:

[Xun Nan, your mission is to rewrite the villainess's fate and win the male lead back.]

"You mean that pitiful guy getting bullied down there is the male lead? He doesn't look like much."

[This is an apocalyptic world. Host, you must take this seriously!]

"All right, all right. System, just watch me work."

[...So why did you become the savior? What about the male lead? What are we going to do about him? Huh?]

"System, what are you barking about? Just tell me whether I changed the villainess's fate. As for the male lead, tsk. Wait and see. I'll put out a notice to all of humanity telling him to hurry over and marry me. Problem solved."

[...]

Modern romance world:

You find a drugged, drunk male lead. What should you do as the villainess?

Obviously, sleep with him, get pregnant, rise in status through your child, steal the heroine's story, and claim the top spot.

"Sleep with him, my ass. System, if you keep babbling and come up with another crap idea like that, I'll blow myself up along with you."

Xun Nan curses as he tosses the "dumbass" male lead into the room, then picks up his phone.

"Hello, this is, " "System, you dare cut off my call?"

"We can't order chicken for the male lead."

Xun Nan: "...Fuck. Then let him die. Let him wait until it blows... Don't expect me to sleep with him so he can get a free meal. Does he even deserve that, little bro?"

System: [I'm begging you. The male lead can't get hurt.]

"Fine. Got a Fiji Cup? Get me one and let him take care of himself. That work? Don't tell me this world is so lame that the drug only works if he has a dick."

P.S.:

① This story has no romantic pairing for the male lead. It has a male-oriented power-fantasy style, with satisfying fights.

② The male lead will not turn gay. He will always love pretty girls. His sexual orientation is completely straight.

③ After the male lead enters each world, his body will automatically be replaced with his own. [A certain lowly System is forced to agree to its Host's illegal actions.] System: A knife is at my throat...

④ The male lead is powerful and handsome, but not pitiful. He's adored by everyone, but he doesn't reciprocate anyone's feelings. His whole heart is set on becoming stronger. Satisfying fights!

Theme: Freedom is not doing whatever you want, but being the master of yourself.
