Roses are Wilting

Alright, Aiden, listen up. You thought you wrote a funny with this, huh? Well, let's break it down since you are not the sharpest tool in the shed. It starts cute, with the dude saying some cringey stuff about roses and violets to his girl. She says she loves him too, typical. But then he pulls a 180, talks about the flowers dying (symbolic, you get it?), and threatens her cause he thinks she's cheating. And THEN she says "ah about that", meaning she's guilty. So, the dark and the cringe come from the crazy shift of mood, the violence implied, and her nonchalant reply at the end. You wanted to write something deep, like with that poetry. But it just comes off as a crazy person threat. You made a cringe joke. You're welcome.
