What is the title of this manga tragedy?

I got on m******x & o******a and did advance searches also on g****e, and Eeep!, there is a TON of titles in this genre out there!

THE STORY: (as i recall...)

This girl, who is highly allergic/sensitive to sunlight by some other chronic condition she has, kept her indoors during the day, and so she is only able to go outside at night, to play/perform her music via guitar to people. (she gets burned easily, like a vampire, which she isn't).

One day she fell in love with this dude she saw through a crack through her curtains (i think...), as he was selling snack of some sort from a food cart across the street, from her bedroom window (he had a surfboard propped up on his cart if i remember correctly, so he surfs). Long story short they got together... and then the inevitable hardships *T_T*

I read it maybe last year and i liked it. I wanna read it again... weird.

Wish i remembered the title...

Help?

Arigatou!
