In anime, it tends to be a big, defining experience whenever a character falls in love for the first time. Some characters yearn to be swept away by a dramatic romance, like one of the deuteragonists in NANA. Others are terrified at the aspect of vulnerability, like Maid-Sama!'s Misaki. Shojo and josei anime tend to have the most storylines about first love, some of which have stuck with audiences for decades.
