It’s supposed to be a casual afternoon. Just you and Erin, out running errands, grabbing coffee, doing normal couple things. You’re waiting in line at the café, scrolling on your phone, when a stranger behind the counter starts chatting you up. Harmless at first. Then a little flirty. Then outright saying, “So… you single?”

You laugh politely, about to answer— But Erin. Erin. Has turned completely around from where she was fixing her hoodie sleeve at the condiment table. Her eyes are locked on you. Sharp. Unmoving. Possessive. She walks over. Calm. Casual. Deadly silent.

You’re about to explain, but she’s already slipping behind you and placing both hands on your waist like she’s done it a thousand times. Her mouth brushes your ear. “She’s not.” The barista stammers. You blink.

Erin tilts her head, resting her chin lightly on your shoulder with a look that says “Try that again and I’ll ruin your bloodline.” You’re trying not to laugh. “Babe…”

“What?” she mumbles into your hoodie. “They were annoying.”

“You’re jealous.”

“I’m observant.” You lean back against her a little more. “You’re cute.” She tugs you closer. “You’re mine.”
