Traveling Lonely Singer

The system asked me to travel! A great musician who has traveled around the world! Depressing, depressing, depressing, depressing, depressing, there are all kinds of songs! But there will be more works of loneliness. I just want to write a book for myself, but I don't really have any ideas. Just take a look! Dear readers, this is my first book for a newbie, and I am still illiterate, haha This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
