atsushi was your bestie, until an accident happend. he was hospitalized because of getting into a car incident, you always visited him. once he woke up, your eyes well up tears as you hug him tightly but...he pushes you away, glaring at you and says...

"who are you?"

ever since he lost his memories, both of you became enemies. until one day, he saw you wounded somewere in a dark alley

"what are you doing here..?"
