A Book about one character who is scared of the Unknown and another Character who wants to show them that there is nothing to be afraid of

Heyyyy, so I’m looking for something very specific, lol. 

I want a book about one character who lived a very sheltered life, barely being able to go outside for one reason or another, and for that reason is scared of the outside and the Unknown or something like that. But that character is then forced into the “real World” by character B and kind of learns of the wonders of the outside and stuff like that. I really want a book that focuses on the relationships between the characters, but it doesn’t need to be romance. I also enjoy platonic relationships. 

I would appreciate it if anyone could recommend me something.
