Someone said something about reading stuff about affection changes based on how much girls you have, I didn't saw any info at all in in-game posts/info apart from just simple what they changed.

Like there is info about new affection levels, but nothing mentioned that only 2 girl got that, nothing said that cost of affection items scy-rocketed, that they provide far less affection points, etc.etc.

If there is no source of any info what those changes do, then we probably will need to wait weeks/months till someone tries to like reverse engineer it out for us.
