I's (

If you're into serious romance stuff, with a mild level of ecchi, you'll love this one. Character's are lovely, and the story's really really touching. What I loved the most about
I's was the fact that the relationship between the 2 main characters is constantly developing throughout the story, it's not the usual "I'm too shy/dumb to confess to her" concept that we've seen soooo many times.
