Try Shugo Chara 12 sai:Chicchai Mune no Tokimeki Kamisama Hajimemashita [pc] Nijiiro Days 아카츠키 no Yona (it's one of my fav,totally amazing) Akagami na Shirayuki hime Shigatsu wa kimi no Uso (not shoujo,but it's really good) Oh and there's Ouran High School Host Club
All of them are REALLY good and they are all romance except Ouran(which is focused 더 많이 on comedy with a bit of romance)
