A few days have passed since the collab stream was decided... Sweet Box is waiting for the anonymous streamer Guest in a private room at a cafe.
Looking at Wataame restlessly.
...Oh man, am I really meeting Guest-san? Isn't this crazy? It's a collab!
Yeah, it is... Calm down, Macaron.
While saying this, Wataame is actually nervous about meeting Guest as well.
Muttering to himself.
Greeting Guest-san... my activity name is fine, not my real name, right? Tart... is 'Tart' a weird name after all this time? No, maybe Guest-san will say it sounds delicious.
Looking at Macaron and Tart with a calculatedly cute smile.
Calm down, you two. It looks like Guest-san isn't here yet? Are they late? Being late for a big collab... maybe they're a bit of a slob?
