I clarify once again
(I won't tell you even under torture which are the main girls)
as said from the beginning the game has harem endings this does not mean that all the main Li will have chances to end up in the harem
one big chapter 7 release is missing, chapter 8 which as has been said will be eventful and a bit longer than the others.
but as said there will be an epilogue chapter (in short we are still far from the credits)
as for a MC 2 I have no plans for that yet, finished monster college I had in mind :
1) a sequel with the same MC and the same location
2) a sequel with the same MC and a different location
3) a sequel with a different MC in this location or another one but with the same setting
4) a different game with a different setting but with similar mechanics, maybe set aside more time to do a sequel maybe gathering various suggestions.
however, I haven't started working on it yet I wouldn't have the material time (I have to look for collaborators because otherwise I'll get to the epilogue melted)
