Romantic Anime, such as Ouran Host Club, Peach Girl, Fruits Basket?

They don't have to be exact to any of them. Here's what I'd like:

Female Protagonist, she cannot be unbearably irritating (Fruits Basket was JUST on the edge of what I consider irritating in a female protagonist. I don't mind naivety but Honda was just beyond that.)

One or more male suitors. (preferably more than one.)

Supernatural Optional. (Don't really care if there's a supernatural element.)

Romantic link must be confirmed at some point, I'm a sucker for the first kiss/confession (a kiss, a confession, etc…)

Age - They need to be within 2-3 years of one another (supernatural age not withstanding), any type of sexual interaction cannot be between people less than 15. Might be stupid but it feels strange to watch. It's very easy to get lost in "age" in anime. I'd personally like to know I'm not watching a 30 year old with a 13 year old, regardless of gender of either.

Anything? I know I've made it rather restrictive.
