Where did it say it was a 15min screening? I can't seem to remember reading that and it wasn't on haremking.tv AFAIK.

So, I was wondering maybe it was a mistake thinking the 15 of March 15 as 15minutes like lots of people mistook 4 of April as April 4.

If it was really 15mins, then 6-7min/episode like what you said is likely what's gonna happen.
