It's monogamous, so only one LI per MC. But the way the acts in the game are structured, it's fairly easy to play the other routes (you don't necessarily have to start from the beginning, just before the choice.)
But as of Episode 1, you don't need to worry about locking in. Just get to know the LIs for now.
No overlap/sharing between MCs. Each MC gets their own set of LIs, exclusive to them only. I apologize for the choice of word there, I'm set to update the description to make things more explicit with the release of Episode 2.
Thank you. I try to get it finished faster than my intended deadline. Honestly I think there's more exciting stuff further into the story than what's in Episode 1 so far.
Thank you for taking the time to write this review! And thanks for playing my game. I'm happy you noticed the design of the main menu, it was inspired.
I can't really spoil what's on future episodes, but Episode 2 definitely would be longer than Episode 1. Nicole, for sure, is a popular pick this early into the game.
