The story passes in a far away hospital, away from civilization, that has a dark glassbox around it.
The game features the lives of Lai, an albino who can't be exposed to the sun and lives in the hospital because
the sun is covered by the dark glass and therefore she is allowed to live a fairly normal life.
And Rei, a patient of the surgery side of the building who can't have a surgery.
Will Lai be able to make Rei's live less miserably?
