In order to change the boring and rigid melody, Mr. Pianist started writing a diary.
The diary records Mr. Piano's monthly changes and some of his opinions.
But as time passed, something seemed to go wrong?
It's actually anthropomorphic^^
The copywriting is useless, the writing is useless and the plot is useless, lying on the ground with a happy face
It's probably a warm-hearted one. Because it's a diary, it's in the first person, but there may be a possibility of changing it later...
The main CP is a dull piano gentleman with little emotional fluctuations × a gentle violinist who is an expert in housekeeping
