I was rereading Quick Transmigrating Second Female Lead’s Counter Attack and I still don’t know what it means. To quote it “So is the book NP, or is it NP, or is NP?” I tried searching it up but it didn’t work...
In China,NP can be explained with harem or Reverse harem.It means many people are in love(even they have no love just do…) It can be girl boy boy boy… boy girl girl girl… girl boy girl boy… girl girl girl girl… boy boy boy boy boy… If there are three people,so it will be 3P.In China,this world usually used for a tip with R18 books. Sorry my English is very poor.I think my discretion is silly.:(( I hope nobody know me.
Ahh.. I searched for the answer on google and I found this forum, thank you for your answer, now i am enlightened
