So I am a little confused. Does Saroma like them both? I thought at first she was just a masochist that loved getting stared down.
She's still operating under the [grossly mistaken] assumption that Mikage is in love with her, while Hinata is in love with Mikage (that much is true, at least). She's fantasizing about a drama-fraught love triangle, when in actuality she's just a mildly annoying third wheel. When I think about it like that, I actually pity her a little...
