Elegy (Inuyasha's, especially the one about the flute, which makes me want to cry every time I listen to it)
Missing Over the Times (Inuyasha's, which will calm you down when you are upset! Try it! Ps: This is the background music of many touching videos)
Walking in the Air, also known as Hal's Moving Castle (a very famous movie, and the theme song is also very good! )
the fact that you left (I don't know how to describe this song. Different people will have different feelings when listening to it. Only after listening will you know! )
Sadness or Happiness (This song will make you feel heartbroken if accompanied by the online video! )
ps: These are my favorite songs that I never delete from my mobile phone. I hope you like them! ! !
