Ultra-romanticism is like when you really, REALLY like something and it makes you feel super happy and emotional inside. Imagine if you loved unicorns so much that just thinking about them made you feel like you were on a cloud, and you wanted to make everything in your life have unicorns on it.
Well, ultra-romanticism is kinda like that, but instead of unicorns, it's love and emotions. People who identify with ultra-romanticism really believe in true love and having a soulmate who completes them. They might get really emotional and dreamy when they think about love, and they might even believe in things like destiny and fate bringing them together with their perfect partner.
It's like they're living in a romantic fairy tale world where everything is beautiful and perfect, and they want to feel that way all the time. They might express their emotions in extravagant ways, like writing poetry or painting pictures, or they might just want to spend all their time with their special person, believing that they were meant to be together forever.
So basically, ultra-romanticism is all about feeling intense emotions about love and believing that it's the most important thing in the world.
