When you become unexpectedly overwhelmed by the observation of the opposite gender (or gender of romantic interest) and become besotted by them only having known them from one meeting. Admiring someone you have just met platonically but in a romantic way.

Wearing your heart on your sleeve in the most literal sense.

Basically could fall in love with the idea of somebody by idolising them, filling in the blanks which leads to romanticism.

Changing your mind about what you want in a partner everytime you meet someone new, even if you have never suggested so before, based on one girl after one meeting.
