Smut is welcome but it's even better with a plot which, in this case, started a bit too late, as if a context was needed not to turn the manga into a mere PWP. The plot then was very interesting; I eagerly expected to know more about the whole situation (I don't go into details; it would be a spoiler for those who are about to read the manga) but... nothing. The story ended :/ Probably something more is yet to come and I do hope so.
