This song is originally sung by Kagamine Rin The song is about Nagisa is an assassin,he hates his real parents because they had abandoned him years ago.He wants to assassinate them if he meet them because there's no more love between them.He knows this is wrong but he can't control himself to do it. The memories of he and his real parents hurts himself.He can't take it anymore. Until 2:00 p.m.,he still can't sleep.Those memories keep hurting him.It's fine that he didn't sleep because he's a robot,what will hurt him most is his memory. He ready all the stuffs and walk out from the house secretly.He don't want to let others know that he leaves. He has a old photo of him and his parents.The blue haired baby that's in the photo is him.His mother who borned him has beautiful and long light blue hair and dark blue eyes.He has an older sister,she is older 2 years than Nagisa.She has dark blue hair and dark blue eyes.He also has a older brother,he has red hair and golden eyes It makes Nagisa realise that Karma is not only his friend but his brother.He reaches Karma's house.He climbs through the window which didn't been closed.He walks into the first room.He meets his sister.He don't want to bother her. He then goes into the second room.He walks into it then goes out because he don't want to make Karma angry.He finally walks to the third room.He knows how they really look now.He put down his bag and take out a knife.He's not going to assassinate them yet because he wants to listen to their last words that they're going to tell him. When his parents wakes up,his mother looks at him.She walks toward him and hug him.He never feel something before.He knows that feel now.It's a parents love.He drops his knife.His tears running down.He knows he's wrong.He's not going to simply assassinate others for his own good. In the end,Nagisa joined his real family and he's happy again.All Rights Reserved
