Manga A Girl Like A Pilgrim

Aiko moved to Tokyo out of an adoration for Shinonome Shion, a mangaka whose work touched her so greatly that she reveres them like a god. What she doesn't know is that Mao, her lonely, gloomy next-door neighbor, is actually Shinonome-sensei herself. Their complicated relationship grows deeper as Mao tries to keep her identity a secret while struggling with the pedestal that Aiko has unknowingly put her on.
