Clueless.

( Stalker POV / Murderer POV ) - You've gotten away with it—taking his son, your boyfriend—And so far, nobody suspects a thing.

I did make it vague enough so you can play as a lover who isn't the killer because I don't like being restrictive, but still it was made for the purpose of a badguy pov.
