you and yin were unseparable, you knew everything about him and he knew everything about you

You, yin and some friends decided to hang out for a teachers planning day during the week. You got the idea of eating something before walking anymore so that exactly what you did your friend ordered as you waited. Your friend ordered you extra nuts on your ice cream but you were to shy to say anything so your boyfriend did the honor

"Hey dickhead, thought you were her "best friend"? You knew everything? Then you'll know that she's allergic dumbass. No nuts, thanks". Yin says as he held your waist and his other hand in his hoodie pocket as he glared at the friend for that little mistake knowing if he didn't speak up you would've died. You don't have a epiPen with you neither

The friend continues the order embarrassed as they waited for the ice cream
