I had a random thought. What if the girls automatically gained a tiny amount of xp and affection each time you collect money from them (so long as they aren't maxed already of course)? For example, maybe something along the lines of 1 aff per collection while at 0 stars, 2 aff per collection while at 1 star, 3 aff per collection while at 2 stars, 4 aff while at 3, and 5 aff while at 4.

I'd still want to see the requirements re-rebalanced as well, of course. That would be the primary (and more important) fix, and this collection bonus would just be a bonus on the side. Dial back the scaling factors for raising affection levels, like maybe.... Okay, assuming that this explanation is true:

It uses a x3 multiplier and a modifier for each step, so that's why it gets the results it gets. The growth of the values comes from a pattern in the between between stars rather than the total, it looks weird though.
Suppose that instead of using x3 you use x2.5 or x2 to make the pattern. So something like {15, 50, 135, 605, 1345} or {15, 58, 171, 731, 1854}, from plugging x2 or x2.5 into soviras's math.

Additionally, or perhaps alternatively, I'd ask if "order in harem list" is really the multiplier that you want to apply against those numbers. I mean, whether you dial back those numbers or not you could consider grouping the girls up logically into distinct tiers based on which world they can be obtained in (including the event girls that you get from trolls, although maybe consider setting their tier as being +0.5 over the world they were in). Pachinko exclusives (both permanent and event based) would either have some preset designation higher than the current worlds (for example, tier 10) or you'd have to go through one by one and decide which world each one fits the theme of and match them to that tier (or +0.5 over it).

A scheme like that would achieve the same stated purpose of making affection easy for brand new players (Bunny, Juliette, Red Battler, and Ankyo would be "tier 1" so they'd all have the {15, 65, 215, 915, 2665} set as the required values to reach each star level (to use the current multipliers for this example)) and progressively harder as a player gets further into the game (Agate and the world 2 troll girls would be "tier 2" so their stars would be at {30, 130, 430, 1830, 5330} affection, Jennie and the world 3 girls would be "tier 3", and so on) but we wouldn't be seeing the numbers explode to insane heights (especially compared to the values of the affection items) when we get up in the range of 30 or 40 or 50 or so girls in the harem like the "order in harem list" scheme does.

Wow, I really went off on a tangent away from the thought that I started this post with.
