After a breakup, a song heals the world

There are so many pains in this world. If you have them too, please let me heal them with my singing... I traveled through a parallel world and became an art student who committed suicide after a breakup and depression. And awakened the healing singing god system. After being successfully admitted to the music school I had always dreamed of. At the welcome party, a song "Under the Sea" healed the whole world. It also made the girl who broke up with Su Yan regret it. Everyone thought that "Under the Sea" was his peak, but they didn't expect that it was just his starting point...
