“I’m sorry… I just can’t be with anyone but him anymore…”

“N-No way… Aki, that’s a lie…! Please tell me it’s a lie! Weren’t we lovers!?”

In the pouring rain, a lone boy cried out in despair, not even bothering to open an umbrella.

He looked like a high school student. His school uniform was soaked and muddied, and his pitiful appearance stirred sympathy in anyone who saw him.

And before him stood a girl, wearing a conflicted expression—a mixture of guilt and ecstasy. In contrast, the handsome boy holding her in his arms wore a sneering smile.

“—Honestly, it’s about time you faced reality. Between the two of us, who’s the better man? Still can’t tell?”

“Ah… Aaah… no… don’t go, Aki…”

Drenched from head to toe, the boy reached out toward his lover—no, his former lover—with a tear- and rain-streaked face. But the girl averted her eyes and delivered her cruel farewell.

“I’m really sorry… Goodbye, Hiro-kun.”

“Well, that’s that. So, stop messing with my Aki, alright? Let’s go, Aki.”

“Y-Yeah… ♡”

Her cheeks flushed, the girl leaned into the handsome boy under the same umbrella. They walked away, embraced together.

“Ah… aaah… aaaaaaaaaAAAAAAAAAAAAAAHHHHHHHHHHHH—!!!”

A scream erupted from the boy as he witnessed the scene. It sounded like the death throes of a mind breaking apart.

It escalated into a blood-curdling wail.

“Uwaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhh!!!”

--------------------

“………………”

“What’s wrong?”

Noticing the handsome boy suddenly stopped walking, the girl looked up at him.

He appeared to be watching her ex-lover sobbing behind them.

“—Ah, it’s nothing. You’ll get wet if you don’t move closer.”

“Kyaa ♡ I-It’s hard to walk if we cuddle this much~ ♡”

Caught up in the haze of lust, the girl didn’t notice.

She didn’t notice that the handsome boy wasn’t looking at her.

His gaze was fixed on the boy still weeping behind them.

“………………Heh…”

Within that gaze simmered a dark, sticky passion.

--------------------

“Well then, see you at school tomorrow.”

“Y-Yeah… ♡ See you tomorrow… ♡”

After walking the girl home, the boy headed toward his own house.

“Alright then…”

He reached into his school uniform pocket and pulled out a pair of earphones—an expensive model he splurged on with money from his part-time job. He was picky about sound quality.

He connected the earphones to his smartphone.

“…Hurry. Hurry, hurry…”

His fingers moved busily. What he opened wasn’t a game or video app.

“Uwaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhh!!!”

“…Aaaahhh~ the sound of a brain breaking is just the best~”

His handsome face twisted with a wet, sticky smile.

He was a piece of human trash, a total sociopath.

To make it worse, he harbored a desire to become a woman and suffered from an excessively deep kink of wanting to be NTR’d (cuckolded), while having a healthy relationship with his lover. Since that was impossible in a male body, he instead seduced couples at school one by one, destroying the boyfriends' minds to try and quench his unfulfilled thirst—a depraved pervert whose very existence was shameful.

“Hiro-kun’s despair is just chef’s kiss! And Aki-chan’s slut performance? Totally Oscar-worthy!”

The worst part: he didn’t even bear malice toward the couples he ruined. If anything, he felt grateful to them for giving him such beautiful “brain-breaking” scenes. He probably thought they deserved to be paid.

To put it mildly, the world would be a better place if he dropped dead.

“——Huh?”

Perhaps the world’s prayers reached heavens.

Or maybe the god of traffic safety had had enough.

A truck, ignoring a red light, came barreling toward him at full speed.

That was the last thing he saw.

--------------------

But if there’s a god who punishes evil, then surely there’s also a devil who preserves wickedness.

After being dragged several hundred meters by the truck and turned into modern art, he suddenly found himself an infant.

“Waaaah!”

Moving his barely stabilized head, he checked between his legs. That thing he’d had in his previous life… was gone.

Apparently, he’d been reincarnated as a girl.

He—no, she—thanked the gods.

She’d been given a chance to realize the dream she never could in her previous life:

To be NTR’d while having a pure relationship with her boyfriend!

In her past life, she could only play the role of the other man, but this time, she would be the female lead in an NTR scenario—a trashy bitch character.

Hell yes, this is gonna be awesome.

With the excitement of a young actress landing a lead in a Hollywood blockbuster, the world’s most wicked baby burned with a fire darker than the abyss.

And somewhere, the devil who granted this reincarnation probably tilted their head and muttered, “Maybe I shouldn’t have done that…”
