I'd suggest a Natsumi x whoever the other character was, cause of the interactions.

whoever the other character was

You haven't seen Sketch? You poor, deprived individual.

this was nice

Cute I always wished that Natsume got more screen time I felt she was an underused character.

Reminded me peanut-bhtter lotion thing. leggylegs.

this made me feel bad for natsume...i really wished she got more time in the manga and in the anime
