Sakura-sou no Pet na Kanojo, Nagi no Asu kara Recommendations
There have been many shows that features a group of friends having love interest with each other and/or one of the character in the group will fall in-love with someone foreign to them and Sakurasou no Pet na Kanojo and Nagi no Asukara are example of the said theme. While Sakurasou does not feature supernatural creatures like Nagi no Asukara but features weird people, they both have the same feeling and the most important part of both, the characters' development that improves the show more.
Far from being a generic romantic comedy/drama, both convey deep feelings within one's self with fantastic art, incredible plot and an endless roller coaster of excitement for what's to come after each episode.
Truly, what makes these two so alike is that the story and their characters are incredibly and realistically human.
Both are very character driven slice of lives, nagi no asukara has a very nice twist to it and they have very similar character dev, both are great!
Both have top notch animation too xD
Both shows are driven by each character's love interest and the growth of these characters as the show progresses in the slice of life manner. Although the setting varies differently between the two shows, this does not prevent both them from having a similar effect, to get you attached to the characters and watch them grow in terms of their relationships and their individual characters.
