After meeting at a garden party Uriele and Glyss probably met in secret a couple times a week for a few months, up until Glyss murdered Auren who had snuck into the garden where he and Uriele would meet in secret. I think up until that point they’d been close friends, Glyss trying to keep some distance, scared of forming attachment. Once the stakes raise I think their relationship will slowly lean more into their romance, I’ve tried to make it a slow burn!
