I cry hard. This manga broke my heart. The way Hikaru B said that he is a failure one. He is just a substitute for Hikaru A. Hikaru B is my ideal one. Even though he is not for household chores or robot, he is close to being a human. Even though he is an android, he has feelings. . But in the end, I do hope there are more chapters of how they ended up being together again in Oze.
