Hatsukoi Limited.

Ayumi Arihara believes that being loved is the ultimate key to happiness—which is why her greatest wish is to have a boy confess to her. A series of unfortunate events leads to her ideal dream coming true, albeit in a nightmarish way: the towering and terrifying Misao Zaitsu confesses his love to Ayumi through a letter.

Mentally exhausted from not knowing what to do, Ayumi collapses in class. A classmate comes to her rescue, carrying her princess-style to the infirmary. This makes Ayumi fall in love with the cute boy, only to realize he is none other than Misao's younger brother, Mamoru.

Feeling caught between a rock and a hard place, Ayumi must decide whether to stick to her idea of love or pursue what she truly desires. However, Ayumi is not alone in her struggles—all her friends are also taking on the challenges of first love, and for teenagers, it is never as easy as it seems.
