A bunch comes to my mind, but if I had to pick a few off the top of my head (i.e., according to my tastes at least, it could differ from individual to individual), the following:
College Daze a lot of content, no grind. I like games with meaningful choices and this games has tons of it, leading to a lot of different paths and scenes, leading to a great replayability.
I LOVE MDRG and Teaching feeling! They're so wholesome, and I absolutely love the romance content in them.
For rpgs, I suggest both Strive: Conquest, and Love & Corruption! (no, it isn't a corruption game). They're both super long games, and also really fun!
Both have absolutely amazing romance content and wholesome sex scenes so thats a major plus
