Im looking for a shoujo (which has an art usually found in ecchi) in which a schoolgirl had a crush on a boy in the same class, but never got the courage to confess to him. She noticed that he took a liking to the pretties girl in the class and nearly gave up on him. One day a female fox kami gave her the power helping her transform into anyone she wanted, she made use of that to approach the boy and caused some incidents, so that later on found out that the boy also liked her back.
The female fox kami might end up with the FL’s megane big brother
