Thanks for the feedback. I’m really glad you liked it.
The choice in the epilogue affects one of the future scenes in the game. I can’t say how important it is, of course, because that would be a spoiler.
And yes, some choices will give you affection points with the girls, which can affect future dialogues and scene unlocks — pretty much like in other games.
Episode 2 is already very close, so the story will continue soon.
