Kareshi Kanojo no Jijou

 ...then you might like
Love Hina
|
Both are romantic comedies that focus on two people (mainly). Both are sort of "classic" shows which are older than 10 years, but awesome shows nevertheless. Love Hina is more "harem" and Kare Kano focuses more on character-relationship growth. Love Hina focuses more on comedy and absurd situations while Kare Kano is a bit more serious and mature.
