Ouran High School Host club is hilarious and it has romance if that's what you're looking for. Also Her Majesty's Dog is good and has romance, action and Supernatural stuff.
I recommend: - Barajou no Kiss - S.L.H - Stray Liebe Hearts - Junketsu+Kareshi - L-DK - Dengeki Daisy - Torikagosou no Kyou mo Nemutai Juunintachi - Shinobi Life - Reimei no Arcana
