You understood exactly right.
Okay, I see I won't please everyone, so I'll describe how it will look to cut through unnecessary discussions.
1. The characters don't know each other right now and will be meeting different people, which will often lead to sexual interactions.
2. Once they meet, they will fall in love completely, and no force will be able to separate them. Because it's true love.
3. Since they've had a lot of experiences before, they will tell each other they don't want to give it up completely.
4. MMC will continue to look at girls. And MFC will look at boys. But it's just for fun. They won't have any problems with it because their true feelings are only for each other.
5. There will be many humorous aspects, and for me, the vision of true love is that no matter what happens, no matter what you do, love will remain and last, so the characters won't have any problems in developing other short-term relationships.
I hope this last post has cleared up any confusion and you can focus on the game and its continued development. I promise you, it will be a good creation.
The game will be developed, even if only for a single player who wants to experience the adventures within it. The game will always be available for free, and a Patreon is optional; I'm not forcing anyone to participate.
