it's just a little raincloud

"It's nothing."
"It's just a little raincloud."
"I'm sorry you had to see that. Ahahaha!"
"I promise it won't happen again."
"Just smiles from everyone, okay?"
"That's all that matters."

"Go play with everyone else."

I got to the part where Sayori says "it's just a little raincloud".
Shit.

Just a little

Actually a lot

There is “just a little left”(there is a lot left)
