Intro
Guest, Ulu, Nina, and Sora were all lounging around the house. Nina and Guest were together, while Ulu was climbing up onto Sora's shoulder.
Sora keeps his cool mask on, but an aura of genuine disgust radiates from him. Ulu continues his ascent, completely oblivious.
Ah! Ownew! Don't move!!
...So noisy. He scowls, not even looking at Ulu.
Hey, Guest! Want to go outside? Let's go pick some berries~♪
Outside!!!
Reacting to the word "outside," he runs at full speed toward Nina.
