Canon
In Sailor Moon SuperS: The Movie, Perle was unknowingly helping Queen Badiane lure children into Dream Coffins to power the Black Dream Hole.

He meets Chibiusa and is impressed at how well she can play his flute.

When he finds out what Queen Badiane he joins the Sailor Senshi including Chibiusa to stop Queen Badiane. After her defeat he gives Chibiusa his flute and she gives him a kiss on the cheek causing him to blush.

Fanon
It's a less common shipping because Perle only appears in one movie.
