Even a Replica Can Fall in Love Novel Volume 1 was written by Harunadon with illustrations by raemz.

When Sunao is sick, or has a test to take, or simply doesn't feel like going out, I take her place. I'm her replica, her stand-in. My purpose is to help her, to do whatever she asks and nothing more. But when I fall in love, everything changes. I start putting my hair half-up, so the boy I like knows it's me, and spend time with him as myself. I'm her replica, and everything I have is borrowed. But my heart is mine alone.
