I don't think its going to matter on how much MC fucks for the Cindy route, its just have you done it in front of her type thing
True, although I find her reactions in the optional event quite peculiar:
girl "It's not like kissing people has been the worst thing I saw here tonight."
mc "If you hadn't noticed, our parties are usually wild."
girl "But not you?"
if affinity == "DIK":
mc "Sometimes. But it can get too much even for me."
girl "Right. But...you plan these parties."
else:
mc "I try my best to avoid the crazy stuff."
girl "Right. You only plan that for others."
She says both with this look:
Her lines with both DIK and non-DIK seem like she disapproves a bit the way MC plans the parties, her facial expressions however do the opposite.
Also why does MC say "If you hadn't noticed, our parties are usually wild."
As far as we know this is only the second DIK party Cindy went to, and MC doesn't know that xD
