Eternal Love of the Fox

Both are lighter historical/fantasy dramas in which the ML is a nine tailed fox and the FL is human.

Both MLs are supernatural animals rescued and cared for as a pet by the human FL. They then transform into a human and follow the FL across multiple lives, each one ending with the FL's tragic death, some of them including her marriage to someone else, all in the hope they can one day be with her.

Same FL actress and director, same humor and style. Both have a palace setting. Both have a princess SFL and a scene in which she "torments" the SML.

Same FL actress and director, same mix of humor, romance, and more serious moments. Both have a palace setting and a ML who isn't human (nine tailed fox vs. fictional character).
