Sex is fine, but love isn't? How strange.
Huh? Their supposed to get sexual guidance, but love is a no-no. That sounds suspiciously like training prostitutes. Except they are somehow supposed to retain purity. This all sounds so confusing.
I'm still baffled about this. Same point I made few chapters back when I started noticing how the manga was straying from the sense of purity, without actually touching upon it.
