Just watch Hentai.
Nisekoi is good one yeah it also based on the same harem based concept but still it is good other than that I prefer romantic anime over romantic manga so I don't know much romantic manga
Watch the first season and then leave.
But manga is gonna end pretty soon and it's becoming more and more interesting that what is gonna be the final decision of raku and secret about the book
Well the story is kind of unbelievable with lot of coincidences and all, but I too liked the anime. Never tried the manga and never will.
Ehhh..I sort of envy you all. I was so traumatised by School Days that I fear watching anything with 'romance' being a major plot point.
