InuYasha

 ...then you might like
Maison Ikkoku

Both were written by the same author.
Both Maison Ikkoku and Inuyasha feature a similar style of romance between two main characters that's bittersweet, long-running, full of misunderstanding but still mature. Since they're from the same author the characters often feel very similar albeit the setting and time is wildly different.
