This series is divided into two parts. Part 1: Lian's perspective (episodes 1-5) Part 2: Rina's perspective (episodes 6-10) Lian's perspective: Lian, who is naturally smart and cheerful, advances the course of his life easily. However, the city of Tokyo does not easily allow him to have a peaceful and happy life. The prank of fate has intertwined the fates of this man and woman. Why do I think about it now? Rina Aizawa, a classmate who was arrogant because of her youth, why do I think about her eyes, voice, and the warmth she gave me now? At that time, we were not complete. In order to find the inadequate parts, we were hurt, but we still had to look for them wholeheartedly. That's why we didn't realize that irreplaceable things have always been around us. Rina's perspective: Rina (played by Akane Horita), a beautiful girl who wanders among the people, is infected with the atmosphere of the big city, and is strong and clumsy in creating her own life. It stands to reason that I should live a happy life, but in my heart, Lian (played by Yuki Izumisawa), a classmate who accompanied me through my youth, is always sleeping. Do you still remember us back then? A life that everyone envies, a wealthy lover, nothing is unsatisfactory, but... This perspective truly depicts the lives of a man and a woman intertwined in mischief, telling the story of Rina.
