(sorry for my english haha)
I remember that it was about two stepbrothers, one was Yakuza and the other was not, the one who was not Yakuza, his stepbrother treated him badly, the adoptive father also did it, I remember that the Yakuza brother loses his memory because he was stabbed or shot, the truth is I don’t remember well, the thing is that in the end the two fall in love because the stepbrother became good
I think it was canceled because the artist died
