Dear Antique,

Overview

In a world where androids are bound to always serve humans, the android mechanic Marius finds Misha, an antique android who has lost his memories. Seeking a new master, Misha sings songs and sometimes refuses human commands. Is Marius's interest in Misha, who defies android norms, just mechanical curiosity... or something more? Around this extraordinary android, the world of humans and robots begins to turn— This is a tale of love that transcends biology.
