Short game with 8 endings. Explore the dialogue and story yourself but if you want to read about the endings, here's the spoiler warning.
1. Ending 1 - The Bad Guest (leave right away when you can right after the dialogue ends, confirm to leave)
2. Ending 2 - Unhelpful spiritual guide (not sure why spiritual guide is not capital like Bad Guest is, but there's multiple ways to get this ending, by basically answering in a non-caring manner)
3. Ending 3 - Blindness (choose "Just kids stuff..." when ask what her son said)
4. Ending 4 - Abandoned (leave the house once the boy disappears, basically it's a big NOOOPE)
5. Ending 5 - Into the Rain (multiple ways to trigger it, as long as you leave once you start talking to one of the 3 possessed people or after reading only one of the letters)
6. Ending 6 - Coward (Leave after reading the two letters)
7. Ending 7 - Taken by Darkness (Do nothing after reading the letters or say no at the end)
8. Ending 8 - The Faithful (Keep praying at the end)
