It's not easy to quote other visual novels than the ones you've already been advised...
I found a visual novel that offers the exact opposite of what you're looking for XD a protagonist who seeks revenge and recruits heroines to help him in his quest for vengeance
If you're interested, it's Revenge Story (https://vndb.org/v34586) which is still in its demo stage... Discovered on Kickstarter
But it's really the exact opposite of what you're looking for
