i ended up writing a book end, but the story doesn't end here still

it would be a nice way to end off the entire vn, but there's still loose ends i left intentionally to tie up in this last part

question is... because the story centers around these two characters in the second part of the story, and all the side characters either died or haven't had much use in the previous parts, the question is how do i make them more useful during this last part which REALLY focuses on the pairing?

this basically resolves the protagonist's character arc, now for her love interest, and also how will i get to wrap everything else up in a nice bow?
