1. Kare Kano (彼氏彼女の事情 Kareshi Kanojo no Jijō, "His and Her Circumstances")
We wear many different masks in our daily lives - the perfect student, the class clown, the tough guy - in order to gain acceptance from the ones we love. Kare Kano's Yukino Miyazawa and Soichiro Arima learn this lesson the hard way on their bumpy road to true love as they manage to hit every pothole along the way.
2. X (エックス Ekkusu), also known as X/1999
Certainly the darkest couple on this list, X's Sorata and Arashi's romance is so intense that neither of them may survive it (or the apocalypse; don't forget about that). Sometimes it takes a hot-headed womanizer (Sorata) to melt an ice queen's heart and a strong, proud woman (Arashi) to knock Don Juan down a few pegs.
3. Oh! My Goddess! (ああっ女神さまっ Ā Megami-sama), or Ah! My Goddess!
While the plot of Ah! My Goddess may be fluffier than some of the other entries, Keiichi and Belldandy's undeniable charisma and chemistry carries the series, bringing more smiles per capita than most. Besides, what guy wouldn't want a goddess as a live-in girlfriend?
4. Fruits Basket (フルーツバスケット Furūtsu Basuketto), sometimes abbreviated Furuba (フルバ)
Despite its sillier moments, Fruits Basket is a rather dark, depressing anime and the impossibly kind Tohru Honda is the light at the end of man-cat Kyo Sohma's abused, neglected tunnel. We must have been watching it in 3D when they hold each other in the rain during the finale because our faces were soaking wet.
5.Sailor Moon, known as Bishōjo Senshi Sailor Moon (美少女戦士セーラームーン Bishōjo Senshi Sērā Mūn, officially translated Pretty Soldier Sailormoon or Pretty Guardian Sailor Moon)
The term "star-crossed" comes to mind for more reasons than one when thinking about the relationship between Sailor Moon and Tuxedo Mask, but, as the saying goes, opposites attract. This is, perhaps, the quintessential anime love story and if you disagree, well, you're a Meatball Head.
