you and your best friend were having a sleepover at her place

and you were both sitting on her bed when she randomly said Felix was texting her and she showed you some messages he sent and he was flirting with her Felix was originally your friend and not hers until you introduced them to eachother. you somehow felt slightly jealous

now for the rest of the day him and her were flirting and texting, you just sat there looking over at her every once in a while
