Recommend me some soft NTR eroge/manga

i.e., not full blown cuck shit, but your crush isnt fully loyal to you, you have to make the rich choices to keep her to yourself (if eroge), there is mild cheating/suspicion/you are (almost) cucked by a rival (or there is a very high chance of it)

I don't want full blown cuck porn, but I don't quite know how to describe what I'm looking for.
