Nagareboshi

Tensei is a college student who's a hobbyist photographer. One day while taking photos, he encounters and becomes captivated by a boy with burn scars on his face, Makito. Worn down by people staring at his scars from an accident, Makito escaped the flashy modelling industry and instead found work at a small-town library. Tensei, who knows nothing about this past, comes to talk to Makito whenever he borrows and returns books. He begins to fall in love with Makito's delicate and beautiful profile, and before he knows it, he's pointing his camera at him. He's hopelessly attracted to the way Makito looks in his photos. But, as he realizes his overwhelming feelings, a guy from Makito's modelling past shows up to take him back...?
