Hello again... :-)

So I'm looking for a shoujo manga.... I don't remember much about it, and what I do remember is somewhat generic, so Idk... Well, here it goes...
A high school girl is suddenly confessed to by her childhood friend (who has light-colored hair, and is the loud, obnoxious, immature type, if that helps). If I remember correctly, they were near a tree or something on the sidewalk when it happened... They start dating... The girl starts hanging out with one of the guy's friends (he had dark hair and was somewhat reserved). They're hanging out somewhere and her shirt accidentally comes open a bit and he can totally see her breastacles... And he gets all awkward and turns away and tells her.... I stopped reading around that time because it was still being updated, but I had the impression that he was starting to like her....
Sorry, that's all I remember. I know it's super vague, but I'm desperate to find this manga. I read it on another site and I've been looking for it FOREVER.... It's the last one on my list of manga that I want to find... Please and thank-you for your help. ヾ(❀╹◡╹)ﾉ~
