Why can't you notice? | A Mahiru x Sato story

Sato would do anything to protect Mahiru. They've been best friends for as long as Sato can remember. She doesn't even deny that she has feelings for Mahiru anymore. The only things getting in their way were the blonde haired bitch, Natsumi, and Hiyoko, Mahiru's other BFF. Sato comes up with ways to get rid of the competition, and win over Mahiru's heart.
I do not own the cover art, nor do I own the characters.
Might deal with abuse or self hatred later on.
