ah you mean like a more aggressive heroine? there was Tonari Kaibutsu kun, i think- i mean it was a pretty short manga and the characters weren't very aggressive but they weren't afraid to show their affection either. It was pretty popular, and a lot of people liked it. It's pretty recent too.
I'm currently following Sukitte ii Na Yo. The main pair get to be a couple early in the story so it's all about character growth from there on.
There's Kare kano, it's kind of a classic but the relationship between the two main characters is so well-developed. They did go through the shy and awkward phase but only for a very short while. The rest is how they overcome their own insecurities and challenges now that they have found strength in each other.
I wonder if you signed up for the collective reading?
