Violeta and Smoke had a relationship that turned him into bones.

Let LOVE sing it's SONG

In a surreal, post-breakup limbo, Violeta —a necromancer— turns her ex-lover Smoke into bones during a heated fight. Trapped in a ghostly train that symbolizes their failed relationship, Smoke lies dormant… until Violeta passes by once more. What follows is a strange and emotional chase, a dance through memory and regret, as the two are pulled back together in a haunting, silent reconciliation.
