She decided to support his claim to throne differently than originally intended, but she hasn't made a decision on whether her feelings for him are more than friendship yet. Meanwhile, she knows his feelings. Suggesting to kiss for real while she's waffling on the subject and knowing he'd take it much more seriously than she might would be kind of a dick move. Which assumes she doesn't care about stuff like first kisses, but if she does then her own uncertainty on her feelings is already reason enough I suppose.Hahaha poor Noah!
Why not just kiss for real though? *lewd meme face*
