A Song to the Sun (2006)

Amane Kaoru lives a night life, not because she wishes so, but because she is infected with the xeroderma pigmentosum virus. This virus defects the ability to repair damage caused by the sun's rays. Although she cannot expose her body to the sunlight, she dreams of becoming a singer, even if remaining positive has been ruined many times due to her illness. One night, playing outside, she meets Fujishiro Kouji, who has lost his job and hope, and becomes someone who reminds him of his long forgotten music ion.
