Thanks, cool. But my question still stands. For what reason there is 20 characters in this story? What purpose does it serve? Just curious.
Maybe you missed the colloquialisms, but the guy answered your question. I'll try to be clearer. There are Many Characters because each character represents some kind of kink. There's the horndog, there's the dom, there's the sub, there's the princess, there's the virgin (more than one I suppose) there's the timid, there's the pet, there's the MILF, there's the GILF, there's twins, there's pregnancy sex, there's the tsundere, there's cousin, there's M/D (a few), there's blonds, brunette's, redheads, etc., etc., etc.
This game is also, as he tried to imply, sickeningly sweet in the best possible way. There is much humor and overwhelming positivity in the MC's interactions with his ladies ... even if there's some negative surrounding their situation, he turns that around and makes it a positive for them. Every act between the MC and the LIs is wanted* by both parties (well, except some accidental discharge, but that's not his fault) no matter how vanilla or how kinky.
And lastly, the updates come out every half-month, each focusing on 2-4 of the LIs (unless the O'Reilly's are involved, then it could get up to 6), so if a rotation between most of the girls over a 6-month period is too slow for you, keep that in mind.
Good luck with yourself. (Also, I just noticed how old this post is. Probably got your answer already, but oh well).
*Eventually (this only effects Piggy as far as I can tell, and she's definitely a special case ...)
