Am I the Only Cursed Technique User and Villain in Namimori?

1.

I, Maehara Yuai, am an ordinary, well-behaved student at Namimori Middle School whom nobody pays attention to. But now I'm being surrounded by a crowd.

It's strange. Ever since I transferred here, I've strictly followed Namimori's rules: I don't come late or leave early, I keep to myself, and I don't cause trouble.

That day, a group of people rushed over.

They shouted things like "Tenth Generation" and "bonds," then grabbed me viciously.

"So you're Maehara Yuai!"

I was so scared I started crying.

2.

I've been put under surveillance.

They're suspicious of me. They say that in the future, I'll do anything to bring back my first love, Yuta Haibara, who died young. I'll start a war that engulfs the whole world, blow up half of Tokyo, and even force every man, regardless of race, to dye his hair black or be executed. They say I'm a terrifying villain with no humanity.

I point at myself. Huh, me? I could do something like that...

And who is this first love, Yuta Haibara, who died young? Wait, who even is he?!

Could I really destroy the world for him?

3.

The number of people coming after me keeps growing.

They say that in the future I'll be starved for love and a total pervert, and that I need to be corrected starting now.

Yamamoto says I'll think he resembles my first love a little and will love tying him up and teasing him. Does he look like anyone to me now? Yamamoto, let's talk this out. Don't draw your sword!

A stylish guy with earrings has been following me around, apparently to get revenge. He says he can't forgive me for daring to lock him, a young master, in a dark room... Sorry, if I hadn't been the one who did it, I'd really want to help you call the police!

A handsome, long-haired man in black showed up out of nowhere. He said I was his best partner and asked if I wanted to continue our unfinished work, like creating a world without monkeys. I refused. What did monkeys ever do to deserve this? He smiled like a ghost.

They're all black-haired! I'm getting PTSD just from seeing black-haired men, so... is my future self obsessed with replacement romance too?

Look at this mess... what a huge, black pot to pin on me!

Then I started dreaming, and scenes of the havoc my future self had caused flashed before my eyes--

I want to transfer schools and run away!

[Some tips:]

This is self-indulgent wish fulfillment. I personally love the trope of making an honest person snap.

In the main story, Yuai is a timid, weak, cowardly girl. The villain Yuai is conceptually invincible, loves going berserk and finding replacements, and is extremely overpowered. She casts a deep shadow over the protagonists.

Because villain Yuai has caused so much havoc, everyone she hurt is a little messed up after returning to the present timeline.

The main story is written in third person. The timeline has been changed, and the pairing is undecided.

Theme: You're going to try winning the villain over with love too?
