There is a Harem ending if that is what you mean.
I'm sorry bud, but you don't give me that confidence at all after this many decision between girls,like have mom or daughter,big sister or younger,clone or original,head girl or three student girls,after having to choose this many time only thing is left is to get each girl solo ending,hope u succeed bro, I'm out.
problem isn't that it has 5 girls in harem(there are only 5 ' main girl ' right?) It is that you have included more than 50+ girls in your avn already,and i don't know if you will be adding more in future or not,but for sure a game with 50+ girls and ending with just 5 girls in the end altogether isn't harem avn in my book.
