I'd like to share some more info about the game since I've looked into every script files when making bug fix.
1. Do not change "disp_***"
This functionality is used to display character stats on screen (hence the name disp_) when you click the top right heart icon.
It's not called upon by the game when checking stats. So there is no need to change it.
2. It's better to edit stats using console command than mod the game files themselves
Well it's fairly obvious that keeping the original files intact would save you a lot of potential problems, if there is any. Besides, you will have to mod the files again every time the author releases a new update.
While using console command only affects savegames and can be safely carried over through updates unless he completely ditches the current stats system, which is very unlikely.
3. As of now(v.4) Jealousy is still unused in-game, only Love and Desire are checked
This is, of course, talking about Act 03 only, earlier acts doesn't matter anyways.
I've done a mass search in every script files to make sure of it.
Frankly I would just suggest everyone to make a initial save with every stats in 100.
Right now the "gameplay" part of the game, managing energy/character stats and all that, is completely meaningless and counter-intuitive IMO.
Read the spoiler if you want to hear my two cents.
