Doki Doki Literature Club is a psychological horror visual novel from 2017 where you join a your childhood friend's literature club, consisting of 4 girls: Sayori, Yuri, Natsuki, and Monika.
The game starts off lighthearted however, the story slowly takes a dark turn.

I'm not typically too much of a fan of visual novels, but I still found the game very enjoyable enough to play it multiple times.
