Hannah's future (Patreon)

This scene happens if you don't go on Hannah's route, but if your stats with the current love interest are low, you'll unlock a special scene in which you'll randomly encounter Hannah again, and she can walk now and she has become a popular singer.

It's a sad scene, in which Christine feels regret of "what could have been" (remember it unlocks only if your stats are low which means the current relationship isn't going well).

I don't know why but I always loved such scenes. I know, I'm a bit crazy :P
