Okay this idea is a little weird...but bear with me! I'm looking for the male half in a het PSL. That's the standard part...now the odd part.
You know how people joke about not being able to live without a certain other person? Now what if it was literally true and that when one half of the pair died...so did the other one?
Odder still, these two are twins...
Now...what do you do if your other half doesn't want to live and keeps trying to kill herself?
The sister is a little unstable and much to the chagrin of her brother, she's continually trying to off herself. The brother has no desire to die anytime soon, but he also can't watch over his sister twenty four hours a day. Maybe he's a successful business owner...a politician...I dunno, something lucrative. In the beginning I'd like to have the sister institutionalized.
Now...I'm up for anything we can come up with. Maybe the brother, maybe an orderly at the hospital? Anything.
