Estelle Lumière was Marionette’s ex-fiance from back when she lived in Prance. They went to the same ballet school together and fell in love but… it didn’t work out obviously. After the break up, Marionette moved to Equestria and later joined the carnival as a performer.
Knew Marionette was Bi. Was talking about Estelle. X>
Marionette is actually canonically bisexual. Estelle is a lesbian tho.
