Hatsukoi Monster

Kaho leaves her sheltered home hoping to become more independent. After Kanade saves her from an accident, she confesses her admiration, only to learn that the boy whose appearance made him seem older is still in elementary school.

Living at the same boarding house exposes the difference between her romantic expectations and Kanade’s very childish everyday behavior. His friends and the eccentric residents add to the confusion as Kaho tries to understand her first crush beyond the impression that started it.
