Brother, Silent is a game about two monks who have fallen in love against the rules of their monastery.
The PDF is 7 pages, with clean layout and a great piece of cover art.
To play, you and a person you live with vow not to talk about the game. Instead, you pick a spot in your home and leave each other messages there.
Brother, Silent has prompts and follows a loose structure, but you can decide how long you want to play it for. It could be done over the course of an evening, or played over an actual year.
A lot of what gives Brother, Silent its impact is its structure, and not being able to talk about the game may add a surprising intensity to it. The writing is also quite strong, and does a great job framing the romantic narrative.
Overall, if you're looking to play a romance game with someone you live with and you don't mind the possibility of it getting pretty intense, I'd heavily recommend checking this out. It does a *lot* with only a few words, and it's extremely well designed.
