From Raw Manga Scans:

The first three stories are about two sisters, Komaki and Komachi, and a little girl spirit guarding their family. (1) The first story is about Komaki. She's slighly loud-mouthed and makes it very obvious to everyone that she likes Sakuchi. When she becomes conscious of the fact that she may be a bother to him, Komaki avoids him. Sakuchi notices that things become very quiet and thinks that something is missing. Under the guidance of the spirit, what'll happen between the two? (2) The 2nd story is about friendships between girls and how things can become a little hostile when a boy enters the picture. What will happen to Komachi and Shio's friendship?
