I mean, if she had to choose, I would think that the obvious pick would be the guy that instantly developed a head over heels crush on her. The alternative is the guy that sardonically teases and threatens her, like, 5 times within an hour of meeting.
To be honest, I'm kinda struggling to follow the logic of this story. Our MC is really, really concerned with not going to the empire, but because she's lying left and right to get out of it, they're retorting with solutions I don't really get.
And their sudden attraction to her in general as if there's something they're not telling her is puzzling too-not to mention a little creepy.
