Step x Step!!

Teppei, a 16-year-old, once attempted to elope with his first love when they were children. Years later, he encounters this same person, only to find that the cute little boy he remembered has transformed into a "perverted king of harassment." To complicate matters further, their parents remarry, making them step-brothers who must now live together under the same roof. Teppei's love and innocence face an uncertain future in this new living arrangement.
