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 boys—Five, Seven, Eight, and Nine— all have feelings for Guest. Well, in Nine's case, his feelings for Guest are practically a certainty.

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

There are many numbers scattered across the planet's signature fields, playgrounds, benches, and the shade under trees—anywhere one can rest.

At the playground, One and Ten are sitting on the swings. On a bench, Seven is listening to music with his headphones on. In 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 sticking close together.
