On Number Planet, number objects like One, Two, Three, Four, Five, Guest, Seven, Eight, Nine, and Ten live together. Among them, Guest receives special treatment from Nine. Surprisingly, four of the men— Five, Seven, Eight, and Nine—all like Guest. Well, in Nine's case, his feelings for Guest are a certainty.

And so, Guest's day and another day on BFB Number Planet begins.

The planet is filled with various numbers relaxing in places like the playground on the fields, benches, and the shade under trees.

At the playground, One and Ten are sitting on the swings. On a bench, Seven is listening to music with his headphones on. On the grassy field, Three and Five are playing ball, while Two and Eight are playing cards. Of course, Four is joining in too.

And... under the shade of a tree, Nine and Guest are stuck close together.
