konnichiwa :)

am looking for a japanese drama, i remember i read that the male lead character killed his parents,it‘s an adult drama with violence, sex, drugs

  i saw the beginning of the first episode,it was christmas and a women with long hair was walking the street when 

she saw a man on the floor stabbed with a scissors, and it turned out they were lovers, she tried to come near him but he kept telling her to run,

then we go back in time and he‘s a kid again going back home and he hear his mother cheating on her husband.

Oh that's totally:
Byakuyako (jdrama)
