LovingBatmanWayne
Melanie Anders, who's been living on her own for two years, has never really been interested in who's-who. When she runs into Bruce Wayne, she doesn't even care about who he is. She didn't even know who she bumped into. She just yelled at him.
Bruce Wayne is a rich playboy with an adopted son, Dick Grayson. When Bruce runs into Melanie, he became very interested with who she is. No one has ever looked at him after bumping into him without apologizing. She just yelled at him, even after looking at him.
He soon learns more about her by just watching her every move, not realizing she's doing the same thing. But she learns more things than she should.
