Shirogane Hina and Nakamoto Hiro has been classmates since elementary school. Oddly enough you can never consider them bestfriends or even friends at all. Apart from sharing the same class for almost 9 years, they are also neighbors and were childhood friends. The two are pretty much polar opposites but if fate was kinder, they’d be quite a pair. Hiro was an austere boy who ever really cared about anyone else, well not explicitly, he has a soft spot for Hina secretly. On the contrary, Hina was the type who’d care too much. She was the perfect daughter and the second richest heir of the Shirogane clan. Their parallel lives continued normally until one fateful day. It was her birthday and was also the day when they actually got to talk back again after so long. The joy was short lived since news broke out that she died in a car accident on the way home from school. Hiro was distraught but fate gives him another chance. Waking up in the same day from the past, he plans to alter the future for the both of them. With time running in circles, Hiro finds himself attempting to change fate to his will. Will he be able to save her at the end or will he just run infinitely in the illusion of time?
