Even a Replica Can Fall in Love Novel Volume 4 was written by Harunadon with illustrations by raemz.

Sunao left the choice up to me. Will I live as myself, or go back inside her? I asked for a month to decide, but as Christmas approaches, I already have my answer. I'm a replica created to serve my original-what else can I do? But is that really what I want, deep down in my heart? When Spring comes anew, I must face my true feelings and choose: Sunao or Aki?
