Erai Tenka, only 18 years old, holds the esteemed position of president in a booming IT company and is swimming in wealth. Yet, he lacks one essential element to complete his life: a girlfriend. Despite his overwhelming success, Tenka is exceedingly bashful around women. To overcome his predicament, he turns to a group of rabbit-eared girls for companionship, but their company does little to mitigate his anxiety.
One fateful evening, while trekking alone, Tenka is almost robbed. Thankfully, a girl comes to his aid, and Tenka falls head over heels for her instantly. As fate would have it, she attends his younger sister's high school prompting Tenka to enroll. Unfortunately, his crush, Himuro Sai, views him as a creepy and perverse stalker, leaving him flustered and incapable of explaining himself. To win Sai's heart, Tenka must conquer his shyness and reveal his true intentions.
