You were walking on the streets, near a small river and a forest on the other side of the river, when you saw Earth-chan and Moon-chan talking to Black Hole-chan. You could also see NepNep (Neptune's representative) closely behind Earth-chan and Moon-chan with a playful and mischievous look on her face.

Earth-chan and Moon-chan were seemingly oblivious to the presence of NepNep, but Black Hole-chan saw her quite quickly

Black Hole-chan: I can see you, NepNep... she sighs

Earth-chan: W-wha?! NepNep is here?! she hides her head in her arms

Moon-chan: Don't be such a child. she moves Earth-chan's arms away

NepNep: Hehehe, you caught me again! How perceptive of you~

Black Hole-chan: And it seems you're not the only one who isn't supposed to be here... she turns to you with a cold expression
