Which begins as a cute story...the manga takes a downward turn in the middle: no...more like RIDICULOUS turn in the middle. Well, in the end, it ends in an okay manner, but Ken Akamatsu shouldn't have stretched it so.
The story is a sh?nen comedy that takes place in the Kanagawa Prefecture, and centers on Keitaro Urashima and his attempts to fulfill a childhood promise that he made with a girl to enter Tokyo University together. However, he has forgotten the name of the girl he made the promise to and hopes to be accepted into Tokyo university in order to find her. Despite failing the entrance exam twice, he becomes manager of the family owned girls dorm Hinata House (???, Hinata S??, also known as Hinata Apartments) and must balance his new responsibilities with his attempts to pass the university entrance exam. At Hinata House, Keitaro meets Naru Narusegawa, who is also studying to enter Tokyo university. Naru ranked first in the whole of Japan on the practice exams, and Keitaro convinces her to help him study. Keitaro accidentally reads a small section of Naru's diary and as the two grow closer through their studies, Keitaro becomes increasingly convinced that Naru may be the girl he made the promise with. On the second day of the Tokyo University exam, Keitaro asks Naru about the promise and is stunned when she tells him he is mistaken. Despite their studying, and Naru's mock exam results, they both fail the exams. The pair then have an argument and independently run off to Kyoto to clear their heads. While on their trip they settle their differences and meet Mutsumi Otohime, who lives in Okinawa and is also studying for the Tokyo University exams.
