Kai Yaotome is a 6th grader. The girl who moved in next door seems a little different! Because they're elementary school kids, they eat lunch at school, have likes and dislikes, and sometimes forget things... because they are elementary kids. Because they are next door neighbors, they casually hang out, and their parents get along with each other... because they are next door neighbors. An elementary school neighbor comedy!
