Nekota no Koto ga Ki ni Natte Shikatanai.

From Lucia Rose:

Amane Mikiko, better known as Mikki, is an elementary school student who moves a lot and has to transfer schools often. As soon as she makes friends, she has to painfully say goodbye to them. She is determined to not make any new friends at her new school, but it doesn't exactly go her way... especially when she meets a boy with the head of a cat! But hold on... he only looks like that in her eyes?!
