1. There’s a hospital in the background and there’s a nurse in the middle of the screen. If I remember correctly, the song is about there was a cure for unhappiness and so everyone went to the hospital, but because of all the bells ringing, the nurse went crazy and switched the cure with poison to kill everyone (the hospital in the background bounces to the beat)
2. I think Rin sang this song. What’s really unique about this song is that she spins and the blue dress spins along with her. I think she also has one eye.
