Blue Spring Ride (2014)

When she was in middle school, Yoshioka Futaba met Tanaka Kou whom she had mutual love. After Kou moved to Nagaski with his late mother, Futaba lost contact with him. In her first-year of high school, she met Kou who's now carrying the name "Mabuchi", who is now stoic, cold, and totally different from the gentle Kou he met in middle-school.
