Delicate Taboo

The day after Johny turned 18, he was witness to something that changed him... or not.
It's a story about multiple family members and how their choices reshape the way how they will end. They are 6 family members in total. Each male member would have at least 2 love interests and your interactions with them will define the ending, which could be very bad or very good (or anything in between). It will have multiple "game over" that could be seen as tragic, but if you play your cards well enough, you can keep your adventure going without many issues.
