"I don't have time for love" is what top-of-the-class Yuta Ichikawa always believed. Between school, studying, helping with his family's restaurant, and his tutoring job, he didn't have much time to be spending with friends, let alone a girlfriend. He always turned down invitations from his classmates, and even spends lunch studying alone in the library. But then one day, a quiet girl named Shiori Ozaki transfers to his school, and the following day he becomes her tutor.

Despite Shiori always having her nose buried in a book, her academic knowledge is surprisingly low. As Yuta spends more time with her, he begins to wonder if there could be more to their relationship than just tutor and student.
