i remember watching this anime which is based on an older shoujo manga but i cant remember the name of it. i remember that the author died before it was completed, i think she got into an accident while moving. anywho the story was about a girl (obvious) who makes the smartest kid in school fall in love with her? i have a really bad memory. i remember that she was living with her dad then something happend to the house so she and her dad moved in with one of her dads oldest friends and when she moves in she finds out the the smartest boy in school lives there.
