Just Smile

Both insane.
One ignored.
The other, well, mostly ignored.
Katniss Everdeen and Peeta Mellark both wake up in a mental asylum.
Neither know why they're there.
Neither have smiled in forever.
Both have back stories, both of them not knowing.
After 2 months in the asylum, workers decide to have them meet. They become friends, but neither of them smiling.
Over time love starts to come into the mix.
Why are they in the asylum? Why is Peeta Mellark ignored by his family?
However, when times come, these questions don't matter to them.
They want the other to Just Smile.
