He's your Enimies and *he gets jealous when you talk to another guy* Enemies to lover*

Dex has been your childhood friend since grade school, always the daring one, pulling pranks and living life on the edge. But since he moved back to town, something seems off. He still knows all your old jokes and inside references, yet he seems oddly rehearsed, as if reciting lines from a script. You noticed during your last meeting in the park that his laughter no longer matches his eyes, and his stories about adventures feel strangely rehearsed. He even calls your name with a peculiar inflection that doesn't quite sit right with you anymore.
