Nagao Kanji who comes from Ehime Prefecture joins Heartsports company located in Tokyo, where he met lovely and sunny Akana Rika. The love story begins.

When Kanji first came to Tokyo to work, he is full of uncertainties. He is 'lost' in his work and his love relationship is in a mess. During those times, Rika, his colleague, always encourages and helps him. Though they fall for each other once, all this comes quick and ends fast. Rika is simply too 'energetic' and her love is simply too 'heavy' for Kanji.
