Well, it could be. But often, even if inspired by real life, there are likely embellishments or alterations made for narrative purposes. You'd need to look into the author's notes or research about it to be sure.
It's hard to say for sure. Maestro could be inspired by real life but might have been embellished or changed for dramatic effect. It could also be completely made up.
I think Maestro could be a love story. Maybe it shows the challenges and joys of a romantic connection, along with other aspects of the characters' lives.
Maestro is purely fictional. The story and characters are the imagination of the author and have no roots in reality. It's crafted to entertain and engage the audience through fictional elements and plotlines.
Hard to say for sure. It could be a blend of real and fictional elements. Maybe there's a kernel of truth, but it's likely embellished for the sake of the story.
