A class reunion was held for the first time in ten years. Fuka was looking for her ex-boyfriend Yusuke while catching up on her recent activities with old friends she hadn't seen in a long time and laughing about old memories. Fuka was secretly looking forward to meeting Yusuke, her first love. Even now that she's married, somewhere in Kokoro she still hasn't given up on Yusuke. Meanwhile, Yusuke is also captivated by the beautiful and mature Fuka. The two have grown into adult men and women since the time when they couldn't even hold hands, let alone embrace each other. Now, the first love that should have naturally faded away is revived again.
