Seeking [NTR] Games similar to 'A Gentle Girl and A Short Escape'

[treetoto]

I'm curious to see if there are any other games similar to 'A Gentle Girl and A Short Escape' where it is a NTR theme but the MC is basically the only one that doesn't understand that he is being cheated on. Hero Boy Ken is another good example of this

EDIT: I heard that the best way to describe these games is 'NTR Mystery'; which I think just means The MC/cuck will remain obliviously for the majority of the game and the lover will be off having sex but the audience is aware of the situation.

EDIT 2: I'll just start a list here, I won't promise links
Summer Sweepers
A Gentle Girl and A Short Escape 1,2,3
Hero Boy Ken
NTRMAN games: one half of his games are like this
Island prank wars, the full name escapes me but I think this is it

I don't know if it counts, because it's not about gf/wife, but about mother, sister, childhood friend etc: https://f95zone.to/threads/henteria...-tribe-update-15-5-fix-1-n_taii.61811/page-87 (You don't have to play HC1 before, it's a different story). The game takes a long time to get going, but it's definitely one of the best if not the best
