Toki no Maigo wo Sagashite!

Akito's life took a devastating turn at the age of 16, when his parents' accident left him an orphan. He was taken in by Ko, his childhood friend, who had been a constant presence in his life. However, a subsequent accident left Akito with a profound case of amnesia, rendering him unable to recognize anyone or recall any event from his past. Ko, who had harbored feelings for Akito for a long time, took it upon himself to care for his friend, attempting to help him recover his memories. As Ko nurtures Akito back to health, he also hopes to rekindle their relationship, now that Akito's amnesia has created a blank slate for them to start anew.
