Anonono. ~Kimi to Sugoshita Ano Hi Ano Toki Ano Mirai~

The protagonist suddenly returns to those bygone days of three years ago ... Leading a life choked with regret, just wishing that he could have one chance to set things right ... The protagonist is an ordinary college student, living out his tedious days in relative peace. But even through his college life, he feels a kind of disquiet that is hard to place -- the root of which comes from the incidents of a certain failed school festival three years ago. After that time, the life and the friends that he had known were scattered to the winds, leaving him with the life he knows now. But if he had the opportunity to do things over again, to set things right, what would he do?
