Yotsuba to!, Otoyomegatari Recommendations
The story is really different, But both they are amazing slice of life mangas with comedy. They're both really cute. Otoyomegatari is more serious, and is less easygoing than Yotsubato, But they both have the same feeling to it and if you like the one, you'll like the other.
Both are enjoyable slice-of-life series which give off the same mood.
