there's this yaoi where this guy moves into this house and up in the attic there's all this stuff? and he calls someone on the phone that's there and a boy picks up and at first the boy thought it was a prank call since it was late at night and etc, but the guy just wanted to talk to someone and they start phoning each other regularly, but come to find out they're both from two different time periods? and the boy he is talking to that's his old house? and the boy is dead in his time period? the boy does artsy things? that's about all i can remember.
if you know the name to this yaoi please let me know because i can't seem to find it.....
