  Summary

  Killer has been feeling severely neglected by his boss and extremely pent-up with LV that boils under his bones.

  The newbie just happens to be the reason. So, who’s to blame him if he gets a little…
  ”frustrated”?

  TLDR; Killer violently “murders” Cross for being all-that-much “better” than him.
