Set in the 1980s, Initiation Love tells the story of Suzuki, who on a night out with friends finds himself falling head over heels in love with charming Mayu. After a few dates, the two become an item. Time passes and a fitter, more confident Suzuki is promoted in his job and has to move to Tokyo. Both he and Mayu agree to maintain a long-distance relationship. However, the energy of city life and the long weekend trips home provoke a personality change in Suzuki. He finds himself increasingly attracted to his co-worker Miyako and drifting away from Mayu. But, there's a twist in this 'boy meets girl' tale.
