Hm, well, can't say I'm too shocked by the first day sales in comparison to Nanchatte Renai or Shouganai. Kimagure Princess, as a song, fails spectacularly beside those two. It has the type of PV a wota would appreciate, and the general public might not be as...hmm, appreciative?
Hopefully they will break 50k sales for the first week though, if nothing else. I shall remain cautiously optimistic.
