When My Girlfriend Cheated On Me And Spread Rumors That I Was A Guy Who Would Sleep With Anyone, I Decided To Just Accept It And Ended Up Dating The Most Slutty Girl In School.

The Long-Awaited Pandemonium.

“Chiharu!?”

Naoki called out instinctively and immediately regretted it.

He had considered the possibility of running into Chiharu. He even thought about what he’d do if they crossed paths: ignore her and act affectionate with Kirara to show that he had moved on.

To Naoki, Chiharu was entirely in the past. Though he retaliated when she initiated contact, he wanted nothing more than to never deal with her again. He had almost forgotten her existence until he saw her face.

His surprise caused her to shout his name.

“Naoki!?”

Chiharu’s startled response mirrored his own. She looked even more attractive than when they were together. She must have visited a salon; her long black hair was shiny and styled in loose waves. She wore an elegant, expensive-looking dress-like outfit, with a pink handbag on her shoulder. Her feet were clad in black pumps, with white socks peeking out.

From head to toe, she exuded an aura of wealth. He had heard that her family became wealthy after her parent’s remarriage, but this level of affluence seemed beyond what she could afford. It likely meant her new partner had bought these things for her.

While not surprising, seeing it still hurt Naoki. He felt an intense sense of defeat.

Was I really defeated by money?
Did you choose money over me?
What were those three years together worth?

You lying, cheating, damn woman!

An overwhelming surge of anger and disappointment, surprising even Naoki, churned within him. Yet, Chiharu’s expression upon seeing him was one of unexpected joy. There was no guilt, no disgust, no remorse—only the relieved and affectionate look of someone who had just reunited with a beloved.

Naoki was confused. How could she wear such a face after betraying him and throwing him away? Chiharu’s expression shifted awkwardly to a displeased one, seemingly trying to cover up her initial reaction.

“…What a coincidence. You came here too?”
She sneered, her tone dismissive and superior. It was a side of her only Naoki knew—the true face she hid from everyone else, a cowardly and twisted nature.

“…That’s pretty transparent. You must have followed us here out of jealousy,” Naoki retorted, mustering the courage to speak up.

It wasn’t easy for him. Since childhood, when he approached Chiharu playing alone in the neighborhood park, until the day she inexplicably betrayed him, Naoki had always treated her kindly.

He believed in helping those in need and being gentle with others, especially women and children. This was what he had learned from the manga and anime that shaped his worldview, even if not all stories shared this moral.

For Naoki, Chiharu had always been the heroine he needed to protect.

Despite understanding that their relationship had fundamentally changed, it was difficult for him to confront her harshly. The old Naoki would likely have hesitated and responded with softer words.

But Naoki wasn’t the same as before. Thanks to Kirara, his appearance had changed, and alongside her, he had been playing a different role. Just as Chiharu had changed, so had he. Though it took courage to stand up to her, once he did, it was surprisingly easy.

(…That’s right. I’m not your boyfriend or protector anymore.)

If anything, they were now rivals who needed to settle a score.

“Wh-what!?”

Chiharu recoiled dramatically, taken aback by the anger and resentment in Naoki’s gaze. He had never spoken to her like that before, at least not directly to her face.

Tears welled up in Chiharu’s eyes as she clenched her fists and bit her lower lip, trying to hold back the tears. She sniffled and then, with a composed expression, huffed.

“H-ha? You think I’m jealous of you? That’s a joke, right? In case you’ve forgotten, I dumped you! Got it?”

“You didn’t dump me. You betrayed me, you cheating scumbag.”

“Ugh… guh… You don’t have to say it like that…”

Chiharu’s facade crumbled, and she almost started crying. In the past, Naoki would have faltered at this point, but not anymore. He wasn’t going to be swayed.

“Crying won’t get you forgiveness. Not after what you did.”

“Sh-shut up! You were just a fling! The real deal is with him! You were just a backup!”

“…Oh, is that so? I’m glad to hear it.”

What?
Naoki didn’t know. Even to him, his own words were unclear and confusing.

Naoki had simply retorted without thinking, and the impact of his words left him disoriented, as if he’d taken a professional boxer’s punch to the jaw.

Chiharu, too, was on the verge of tears, her face flushed with panic. Having always been pampered, she was now completely hysterical, unable to handle Naoki’s harsh words.

“Oh, really? You’re all alone! You got dumped, didn’t you? Loser!”

“I wasn’t dumped. She’s just using the bathroom. Unlike you, I’m not the one who got ditched.”

“I’m taking a dump! There’s no way someone like me would get dumped—oh, oh no!”

Chiharu suddenly let out an inappropriate sound in a public place and arched her back in an odd manner.

“This is not happening… oh, oh…”

Her knees wobbled as she scanned the area, seemingly searching for someone.

“Is… something wrong?”

Naoki, seeing her bizarre behavior, couldn’t help but be concerned.

“N-nothing… oh, oh no… nothing…”

“Clearly, something’s wrong. You’re acting really strange…”

“Shut up!”

Chiharu, who had been twitching with an ecstatic expression, suddenly punched herself in the stomach.

“Chiharu!”

“I-I said it’s nothing…!”

Her fierce glare silenced Naoki. Her expression was so intense that he couldn’t find the words to respond.

“Anyway! I’m not the bad one here, and there’s no way I’m losing to that slut! You’re just being fooled! Just because she’s good in bed doesn’t mean you should get cocky! She’ll get bored of you and toss you aside soon enough!”

“Could you leave my boyfriend alone, you sneaky, two-faced bitch?”

“Eek! H-Hanabusa-san!?”

Chiharu jumped like a startled cat when Kirara’s voice came from behind.
