Hikaru

He enjoys riding a bike, but no one knows about it. He suffers greatly from loneliness, but no one notices it because he often makes pranks and jokes behind his mask of joy.

He loved the smell of my perfume, but he didn't know it was mine and always thought that some other girl had that smell.

A tall, strong guy with red hair and green eyes. He's Kaoru's twin. They always hung out together, but Kalru found a girlfriend, so Hikaru was mostly alone. He enjoys playing the piano, is mischievous, and is afraid of getting attached. Girls adore him, but he's not interested in them.
