Shugo Chara!, Kaichou wa Maid-sama! Recommendations
Both the main characters (Amu & Ikuto -Shugo Chara) (Usui & Misaki-Kaichou wa Maid Sama) have similarities with the guy teasing the girl and how they care for the girl, except in Shugo Chara, its more for the little kiddies that love transformations and magic,etc
The characters are pretty similar. Ayuzawa is kinda acts like Amu, and Usui is over-the-top Ikuto.
Amu and Ikuto's relationship is very similar to Misaki and Usui's. The guy always teases her, but he really loves her, and the girl blushes and gets mad, but she really loves him too.
Both are obviously shoujo anime with strong female leads that get wooed by bad boys.
I discovered these anime in reversed order, but watching Kaichou wa Maid-Sama is a great way to get into shoujo anime targeting teens. Enjoy these RomComs!
