So I'm finding a manga that I read a while back

It's about this girl who is a tomboy and she wants to become prettier so she asks this guy to help her. Along the way, she thinks she has feelings for his friend who has a crush going for the the guy who is helping her, his sister. But when it came down to trying to confess to him, she came to realize that she was in love with him, the male helping her instead.... I'm really bad at this and I am sorry but pretty please help me find this manga! ╥﹏╥ I've been trying to find it and I want to know the ending. When I was reading it, I don't think it was ever finished （ ｉ _ ｉ ）
