It has been almost 2 years since Mezzo Piano, an introverted Pegasus musician, has been residing in Ponyville, working at Fermata's Piano and Music Shop. He, and his best friend Roseluck, know of his hopeless crush on the local animal caregiver and music enthusiast Fluttershy. With Roseluck's help, he begins to gain friendship and hopes to win her heart.

He has two problems, however. First off, Lyra Heartstrings. She has been obsessively running after Mezzo's heart, which Mezzo is all but too aware of. And second, although he hasn't realized it yet, his heart starts to wonder if he's falling for the right mare.
