いたいあたしあしたあいたい

※Warning: This song contains questionable elements; it may be inappropriate for younger audiences.

The contents in this song are creepy. But the work itself is nice, especially its PV in Nicovideo which you can see it 'moves' even you pause at every seconds. There are hidden contents in 0:13 and 2:52 which make this song more creepier. I'm sad when Nicovideo decided to remove that display in its website, so you can't watch the video with full experience anymore. In case of you want to watch how does the original video look like, you can watch here

About the chart concept at after the beginning part, I must tell you the story behind this. This part in the song was originally split in 2 sound channels (left and right) and combined together. What amazing is each sound channel has its own meaning separately as you can see the lyrics here. So, I intentionally place the notes at left/right corresponding to sound channels.
