Can I somehow unlock the 2 missing hearts with Asaga through the game files?

Finished the game and in the end noticed that every character has 10 hearts except of Asaga. due to what couldn't see her ending. As I learned further, it is because of one of the choices somewhere in the middle of Paladin arc, where you can either get hearts for Icari or Asaga.

I want to see the Asaga's ending, especially when the Gallery is gonna be added in the next update, but damn, I don't want to spend another ~30 hours on the same story. So, is there any way to add hearts to a character through the game file? When I open it in a notepad, all I see is just a confusing bunch of letters and numbers

Why not start New Game+ and play it to completion? Your affection levels and their abilities carry over while the gameplay segments get revamped to make them more difficult.

You'll need to do New Game+ at some point regardless for full completion as it is tied to the secret ending, as well as been an unlock condition for the gallery/music box.

This game doesn't seem to have a lot of replay value since the story is rather linear from what I'm seeing. And after experiencing the whole chapter with the Widow, I wouldn't necessarily want to replay this game with how much of a fever dream that whole segment felt like.
