Sing a Song When Sad

Originally, I just wanted to write a story, a story about a psychiatrist. That profession seems to be such a mysterious and noble profession. Saving a person's body is not as good as saving a person's soul, right? But there must be times when psychiatrists are helpless. Perhaps they have cured many people's heart ailments, but they cannot cure their most beloved ones. The world always operates in the most suitable way, and so do people. So, when you are sad, please sing a song softly. Everything will pass eventually. Ps: Please automatically filter the protagonist's name without any special meaning.
