Actually kinda agree with MC getting mad here. BUT, who knows what that 1 even means, does it mean more like trust or attraction or what, It'd make total sense for her trust level to be in the dumpster no matter how nice he is, time is too short.
Also if they do not mess this up that's going to be some major plot armor. Or what, is it going to be "I'll sacrifice myself for my people" bullshit?
