She is a basic average girl, with a crazy crush on a guy that makes little to no sense. Sure, he may be hot, and you could understand a woman finding him attractive. However, the intensity is just too much to make sense. This doesn't mean the girl's feelings aren't genuine. She may be a Stalker with a Crush and/or a Clingy Jealous Girl. Don't be surprised if the Smitten Teenage Girl gets over her crush and falls for the guy that was "always there for her". If she does get over her crush, expect him to be Put on a Bus. Some Yanderes are Smitten Teenage Girls. Compare/Contrast Precocious Crush.
