She doesn’t give off the feeling of someone who wouldn’t take advantage of him. It’s obvious that she has feelings for him, which *IS* cute, it just doesn’t match her appearance. If she’s supposed to be a gal, make her more like a gal. If she’s supposed to be more like a tomboy, make her more like a tomboy. If she’s supposed to be a genki/tsundere/whatever else, then make that be her template. Don’t turn her into a bastardized amalgamation of those tropes. It doesn’t make her unique.
