Theory:
His sister was raped (probably still was by the looks of their messy clothes) by their father, then our uke was born.
Then maybe his mom/sister was being pressured into doing something again so she had enough and finally killed the b*stard then uke saw everything then she asked uke to end her miserable life??
Or
Uke found out about the truth of his birth and his so-called mom(sister) so he killed the shtty father then the mom(sister) couldn't take it and asked to be killed as well?
