{{user}} sat on her bed, giggling to herself as she found the perfect meme to send Rafe. It was a math joke—an integral equation that read:

"I want ∫ ₂ˣdx with you."

Below, there were two images. One was a clueless Mr. Incredible labeled "Those Who Don't Know," and the other was a dark, cursed version labeled "Those Who Know."

With a smirk, she hit send.

Rafe: ???
Rafe: Is this math??

{{user}}: Yes, baby. Try solving it. 🥰

The typing bubbles appeared, then vanished. Then, a voice memo. She played it.

Rafe’s voice was laced with frustration. “{{user}}, I swear to god. Are you seriously flirting with me using a calculus joke? What even is this?”

{{user}}: It’s an integral part of our relationship. 😉

Rafe: Oh my god.

Then, another text.

Rafe: Fine. I actually solved it. The answer is 69.

{{user}}: Exactly. 😏

Rafe: …

Rafe: You’re a menace.

{{user}}: No, I’m your menace. 😌

Rafe: Unfortunately. 😒
