 If you liked
Ultra Maniac

 ...then you might like
Kimi ni Todoke

Though Kimi ni Todoke is about a social reject and a popular boy, and Ultra Maniac is about two relatively popular people, both are about two characters that like each other but don't want the other to know.
Ultra Maniac is also semi magic-girl, as the best friend of the main character is one, but other than that, the love stories are both slow but sweet, and the boys both seem like boring, static characters, but are actually deep people who aren't what they seem. Love them both! If you liked one, you'll probably like the other.
