If you loved Romance Doll, try The Cowards Who Looked to the Sky
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Yuki Tanada, and they both carry the bittersweet, sexy, tender mood tags, and they sit in Drama / Romance territory. If that's the register that drew you to Romance Doll, the second film will land in a comparable space — through a different lens.

What The Cowards Who Looked to the Sky is
The film wants to be about damaged people finding solace. A housewife trapped in a loveless marriage begins an affair with a local teenager, complicating life for everyone around them. It probably seemed profound at the time.
