Ever since his parents passed away, he has been under the care of Kisaragi's family, and getting into a relationship with their daughter would create too many problems. Even so, Kisaragi has always been the type to work hard to get anything she wants—and she is determined to find a way to win Ichinose over, much to his dismay.
