I don't think it's a true story. Usually, when something is labeled as such, it's more in the realm of fiction, crafted to captivate and take us on an imaginative journey.
It's hard to say for certain. Sometimes stories like 'Maybe Baby' incorporate elements of truth along with fictional elements to create an engaging narrative.
The 'maybe in another life novel' could be about a journey of self - discovery through the concept of another life. It may present scenarios where the protagonist gets to experience different relationships, careers, or personal growth in this other life. It could be a story that makes the reader reflect on their own life choices and wonder about the roads not taken, using the idea of an alternate life as a narrative device.
It could be a story about a group of friends who have tried to start a business several times and failed. However, this time they have a brilliant new idea and better resources. They are hopeful that maybe this time their business will thrive. They might face various challenges along the way, like financial difficulties or competition, but they keep believing that this time will be different.
If 'maybe this time' is from a musical, perhaps it's about a character who has had multiple attempts at something, like finding love or achieving a dream. They are hopeful that this time, things will be different. For example, in a love story, the character has been through heartbreaks before but now has a new chance at love and thinks'maybe this time' it will work out.
It's not based on a true story. 'Always Be My Maybe' is the product of the creative imagination of the filmmakers, presenting a made-up romantic tale for the audience to enjoy.
