I dont know why it gives me goose bumps when they started to sing, especially in the 9th episode where they sing together with their mistress during surgery. 9/10 loved it. And its just too realistic (for me) and characters looks pretty good especially Hibiki-chan my fav with some minor dips in quality. The series seems fair to state about healing power music is expected to have a good music which is they aimed it perfectly and quite unique. Overall, I just can't believe how beautiful this anime is the visuals, the songs. It's just amazing. I was in awe in howthe surgery was portrayed in the song (referring to episode 9). It was absolutely perfect! The post credit scene was cute too.
