These are extras, not even the main story yet. That's why.
Yeah some of these characters don't even appear until Volume 3-4 out of 10 so that's why these are extras.
The story is really really good though. But I don't think the manhua will ever catch up? Not only is there 3P, Double P, S&M, but also cream and fruit involved (and I'm not talking about just putting fruits on top of the body). (⊙…⊙ ) But anyway, if the manhua does cover the whole story, it'd probably get like 9.0+/10.
Someone is currently picking up the novel translation in english from start but it's not quite deep into the story yet.
Check out the new post that I wrote. Mangago hates me.
I don't get why this manHua has low rating. Even if it'still short, it doesn't show that it is a bad manHua. In fact, it has potential considering the other manHua made by the same author. People should at least wait for an update then decide if it seems really worthy of having low rating
