The best romance anime in my opinion is School Rumble. It's the best because it isn't just romance. It's a lot of other genres mixed into one. You get your comedy, action, drama, and everything else all rolled into one.

There are MANY characters but they're all likable and relatable. That series has possibly the best story telling i've seen in any anime in a VERY long time! Give it a read/watch when you can!
