This mod does: Lower the threshold required to trigger main pawn affinity.

This mod does not: Do, or affect, anything else. Literally.

Personally I never interact with my main pawn. Didn't even know romance was an option until I stumbled upon some internet posts. 
A few options to reduce the number of events required to get your pawn to fawn.

100 - Will probably trigger too early if you interact with your pawn a lot. Still pretty early even if you dont 
300 - Personal preference, can't miss the romance flag even if you don't interact with your pawn, will happen naturally tens of hours in. 
450 - A decent middleground if you interact with your pawn a lot but still dont want it to take as long.

Install with Fluffy, lmk if there are any issues. 

Feels kinda silly to grind high fives and small talk. No requests in comments.

A quick rundown to explain what my mod does. 
Your pawn gains affinity every time you do certain actions on a timer (small talk, hi 5's, gift giving, etc, mechanics I never use)
Interactive players probably earn ~30 points an hour, non interactive probably less than 10. estimates below. LMK if you think theres a sweet spot value, all of these are arbitrary choices.

620 (Vanilla): 21 - 62 hours (Never triggered on my first playthrough...)
450 (Eh): 15 - 45 hours
300 (Pref): 10 - 30 Hours (Triggered around 20 hour mark, more conscious of it)
100: 3 - 10 Hours

Your opinion on Capcom's poor design choices are not bugs, and the comments are not forums to request looking into your personal game issues.
