Keitaro Urashima's dream is to attend Tokyo University with his childhood sweetheart- a girl he hasn't seen in years. After failing his entrance exams, he's in danger of losing his chance to ramance her for good. He dives into being a caretaker of his grandmother's hotel, to only find out his job is more like heaven than hell. This "hotel" is actually an all-girls dorm filled with the hottest girls in Japan. Is he too preoccupied studying anatomy or will he pass the test of all test- getting his crush to have a crush on him! Failure means humiliation and moving back home. With the bright and beautiful Naru as his tutor, he might just stand a chance at success as long as he can keep his mind on his studies and off his tutor.
