Hello

I brought the tea leaves you asked for...

Waah, Chino-chan waaait!

No

What do you mean you won't be my little sister any more!? Why!?

I've come to hate you, Cocoa-san

W, what happened...? Are they fighting...?

Hmm?

This is Chino's April Fools prank

She pulls the same prank every year but Cocoa falls for it every time without fail

Truth is, she accepts being the little sister
