It was a pre-destined love and marriage for Sonoko and Tetsuo. They tied the knot and became husband and wife no questions asked. All is well then. Well, perhaps not. Each holds a secret that even the binds of matrimony cannot untie. Sonoko does not know that Tetsuo makes sex dolls or Dutch wives. Sonoko has a secret too. She is about to tell Tetsuo what she has been hiding. Their marriage is already sexless. Will they make it?
Unfortunately the movie Romance Doll is not yet available on HBO Max.
