Help me remember

Kuroo and Suga were best friends growing up as kids. They might as well been stuck together by the hip.
Until Kuroo ends up moving. Which broke both of the boys.
While he was gone, Suga ended up in an accident that causes him to lose all his memories.

When Kuroo finally comes back to town, he has no idea on what happened to Suga. That was until Suga's mother explained what had happened. Will Kuroo be able to help Suga get his memories back? or will Kuroo have to completely start over with Suga?
