Disillusionment
He must be living in a realistic faerie story, a peasant falling in love with the Princess, with all those logical twists and turns that wrench her from his grasp just to seal her behind a curtain of glass (I believe in you).
The curtain flutters every now and then, when he talks to his Princess, and her vital stats trip on themselves (I'm always listening).
But he keeps forgetting, that beyond the curtain of glass and stasis fluid, the world is so very quiet (I'll be waiting).
And maybe, just maybe, they'll make the curtain call together (maybe... I...).
