Onegai Teacher was the best IMO for a romance based Anime. Great ending too, because it leaves a crave, but not an emptiness as a lot of Animes do, such as Elfen Lied or School Days since the endings leave you with a wish to see another type of ending lol. Onegai Twins, Love Hina, Dears, all great and sadly, already seen lol.
I keep clicking into Karin but haven't decided to watch it yet. It seems like a nice Anime, though.
