Even A Replica Can Fall In Love Light Novel Softcover Volume 03

I'm a replica-a copy who must fill in for their original whenever they don't want to do something. But now I've lost my one role. As winter approaches, Sunao begins to scare me. I can't tell what she's thinking at all. While she's away on a school trip, Aki and I visit Fujinomiya, Ryou's hometown. As I enjoy my first big trip, I finally begin to unravel the mysteries of the strange beings called replicas. But am I ready to face the truth of what I am, and of Sunao's secret?
