Suggest me a book with side characters who sees the good/beauty in people or things?

I can only think of one example: Sonja, from the book a man called Ove. She‘s one of my favourite characters ever and she inspires me to be good and happy. She’s joyful and colourful. I have recently started reading last year to cope with my loneliness, so i haven’t read much books and I’m hoping to read more books with characters like her.
