idea/concept of a romantic fantasy

This is a concept for a romantic fantasy WN.

Genre: Fantasy, romance, musical, adventure

MC: A male and a female

Era of the story: Late middle ages, from the childhood of the MCs to their middle age.

Synopsis:

[Male MC name] was born in a magical fantasy world inside a humble small village. He was raised in an average family inside the village. During his childhood, he met [Female MC name] and became best friends with her. However, one day, [Female MC name] suddenly got an illness that put her on death's door. Fortunately, she survived. But as a result of the terrible illness, she lost her sight permanently. [Male MC name]'s dad is a troubadour. He wanted to follow his father's footsteps and become a well-known troubadour. His dream is to write a song that will be known throughout the entire world. He sets out to visit different places in the world as an ordinary person to get inspirations to write new songs. He brought his childhood friend, [Female MC name], who is now blind, with him to all kind of places in the world. To communicate the surroundings to [Female MC name], [Male MC name] think up melodies and lyrics on the spot and sing songs to [Female MC name]. This is the beginning of a romantic musical journey between an ordinary troubadour and a blind girl.

P.S.: This is not a fantasy thats about killing monsters, saving the world and etc. Sure, the MCs will head into dangerous places. However, the male MC is an ordinary person, slightly above average at best. This is a story about the extraordinary places they went to and their adventures, and them finding love during their adventures. Basically, this story has a much bigger emphasis on romance, adventure and character development than plot, actions and goal.

The ending can be whatever, but I would personally prefer the happy ending. (Finding true love and getting married)

Also they won't seek out cure for the female MC's blindness, so please don't do that unless its at the end of the story.
