@Aishiiscool Heyy!!
Firstly, yes. Even though people consider it a mental illness, creating fake scenarios is very normal, especially when you're romance deprived.
And yeah, guys make up fake scenarios as well, maybe not the same as girl's, but they definitely do. They are kinda delusional as well.
And third, it depends a lot on your relationship with people, if you have a guy (or a girl, ldk) that likes you, finds you beautiful or simply best friends, they might make up fake scenarios with you, it doesn't mean that they have necessarily to be romantic. You can make up scenarios with friends as well :)
That's adorable as well and would make me feel very loved!
Hope I helped? Idk ahahaha miss you wifey!
