The heart is a metaphorical thing. I can't run your game for you, but if I were running the game you couldn't just say "I give them my heart", it doesn't work like that. But if someone is willing to have that sort of scene and devote time to that bond, then I think that's worth it.

Absolutely, that sounds fantastic and is definitely the thing I'm most excited about with this game! Just wondering to what extent they then can do the same with another character. Not to be mono-normative, just wondering about the mechanical ramifications of the setup because it seems slightly weird either way.
