Fukuta Jun is an ordinary schoolboy. But he is catastrophically unlucky with girls. To fulfill his wish for Tanabata—to get a girlfriend by Christmas—a graduate of the Heavenly Academy of Amours, Sakai Chris, is sent to help him. She thinks she’s a genius, but in reality she failed the last six exams. Now Jun has a mentor, and girls appear in his life. Which one will he choose, and will he manage to get a pair at all? After all, Amour regularly makes mistakes in her conclusions and is extremely careless with her methods.
