Yesterday, @Zen persuaded me to play Doki Doki Literature Club. I'm not sure if I've ever played a visual novel dating sim before, but it's an absolutely fantastic experience that I would recommend to everyone. There's a bit of mature content, especially if you continue past your first playthrough and into a new game plus, but this is one of the rare cases where I think that the experience is so worthwhile that most people who would shy away from that kind of thing will still take something out of this. And if not, even a single playthrough is a powerful enough experience to be worthwhile on its own.
There's not much more I can say without spoiling it. The poetry in the game is fantastic. And it's worth giving the game the seven playthroughs it takes to unlock the final ending (but you can decide that for yourself after your first or second playthrough).
Zen and I have both given it serious consideration for being our Game of the Year 2017. It's an experience that shouldn't be missed.
