Fruits Basket, Cardcaptor Sakura Recommendations
I think both of these girls are main characters who have magical powers. They are both optimistic, have friends, try to make them happy, and are highly curious. They both have hot-headed guys and friendly people. Not to mention, they have some drama, comedy and romance and are very cute manga.
Both main characters are really nice and makes the people around them happy. There's all kinds of love confusion going on and both have a little bit of supernatural powers here and there. (Cardcaptor Sakura's main character being a magical girl). Don't misunderstand just because the main character in CCS (cardcaptor sakura) is a 'magical girl', it's a family friendly manga/anime, but, it also displays life's problems, just like in Fruits Baskets.
Fruits Basket and Cardcaptor Sakura are two fairly popular shoujo manga that started serializing in the late 90s. The main character is a cute brown-haired girl who had lost her mother, but still remains cheerful and gentle regardless. Along with following her everyday school life, there are also supernatural/fantasy elements such as talking animals and supernatural secrets to keep, as well as some comedic hijinks. The two main love interests are also a gray-haired boy who is nice to her and another boy who gets brash at times.
