What is DDLC
Doki Doki Literature Club. It's a Visual Novel game (not a porn game) that got pretty popular back in 2017 when it was released and it's my personal favorite VN of all time, tho keep in mind if you want to play it that it deals with a ton of sensitive / heavy topics like depression and s*icide, and it's also tagged as 'psychological horror'. It's free here on itch or Steam.
