Both mangas have a heavy focus on the relationship between siblings. In both mangas, the MC older brother is hardworking and lives to take care of their spoiled imouto since their parents aren't around. Of course, without him noticing, some other girls fall in love with him as well. In both mangas, both the siblings have a sibling complex toward each other.
The main difference between both mangas is that Himouto Umaru chan is more focus on comedy and slice of life but Watari Kun is more slice of life/drama/romance.
