In her late retirement, Princess Celestia starts feeling a little blue, perhaps feeling something tugging at her heartstrings that she hasn't felt for some time. In an effort to cheer her up, Princess Twilight sends an old associate of Rainbow Dash named Ace Hart, to see if he can provide her some company. Perhaps the only pony willing to treat Celestia as more than just former royalty, their story plays out in a unique way that shows that it's never too late for love to blossom.
