She's cute, fun, hardworking, and always has the best dialogue in any game. She's a very charming and clever girl who is easy to root for, and getting peeks into her more closed off side (one of a studious, introspective girl who conceals the immense efforts she needs to take in order to keep up with the monsters of Gensokyo for the sake of maintaining her outward facing persona) just makes her even more enticing as a character.
It makes one want to protect her smile.
