LOVE POTION

This was the last thing Kirigiri wanted. In her opinion, dying herself was less painful than having to work with (Y/N) on love potions, Kissing Concoction, Twilight Moonbeams, and Amortentia. Even their teacher, Miss Chisa, was concerned that the two were going to kill each other. So the two just glared at the other, kicking under the table.

Normally, Kirigiri could remain calm, treating others as if they could become like her. But around (Y/N)? She wanted to kick the shit out of her, then Incendio her.

(Y/N) felt the same way, constantly wanting to kill the other. Then again, that was the way with most Slytherins, always having a rival. Like Ouma and Saihara, Hiyoko and Mikan, and Makoto and Togami.

"(L/N), what the hell are you doing?" Kirigiri glared at the girl, who was mixing potions together in a joking manner.

"Oh, well, it looks like we'll both get a bad grade~!" (Y/N) smirked, being one of the only people in the school who didn't care about her grades. She wasn't an idiot, actually one of the smartest kids in the school, but she preferred pissing people off.

Kirigiri scooped up the potion, already pushed over the edge, "If you have the balls, you should be able to down this."

(Y/N) looked nervous, but had a smirk on her face. "I'm a girl, I don't have balls. But, I'll do it."

Sadly, even though Kirigiri was a Ravenclaw, she wasn't aware of how strong a love potion was when you mixed it with multiple others. It's basically a death wish.

(Y/N) swiped the drink, swallowing the entire thing. She looked fine, and Kirigiri was sort of mad. Then, the girl fell to the ground, looking straight at the ground. Everyone was looking at the pair, especially at (Y/N).

Kirigiri was nervous. Did she actually just commit murder? Will (Y/N) be alright? What the hell can she do to help?

Suddenly, the other girl looked up half-lidded eyes. "Kirigiri, I can see why all the guys at our school have a crush on you."

The amounts of "no I don't!"s and "ooo~!"s that went through the room as Kirigiri's face turned redder by the second were uncountable. She didn't know how to respond to her mortal and enemy high-key, un-ironically, flirting with her. That was kind of an issue.

"Kyoko, what was in that potion? I don't remember what I assigned you." Miss Chisa asked, skipping up to her.

"L-Love Potions..." She said, covering her face and looking away. (Y/N) smiled, looking at Kirigiri's flustered state. Kirigiri rarely showed this side, so it was a sight-to-be-seen.

"This wouldn't happen with any other love potion. What kind is it?" The women asked, feeling (Y/N)'s forehead subconsciously.

"A mix of Kissing Concoction, Twilight Moonbeams, and Amortentia." Kirigiri listed them off.

The teacher groaned, "Why would you mix them? In fact, why would you even be drinking them?" It was also rare to this usually calm and sweet as candy teacher mad.

"She mixed them, I put them in a potion, gave it to her, and let her drink it." Kirigiri murmured.

"I see. Well, Headmaster Enoshima can't really do much about this, so you two will be stuck together until I can brew a hate potion." Miss Chisa smiled, looking like she had planned this all along.

And that's how Kirigiri would be stuck with (Y/N) for a couple of days.
