The Sister and the Bride

W-Whoa!

...Hah? Who are you?

Big Sister Suletta's taught me all kinds of thingsー

Pleased to meet you, Big Sister-in-Law Miorine. ♪

What does she mean by "all kinds of things"!? Like when we ♡♡♡ or when we ♡♡♡!?

I'm sorry! She didn't talk about that!

I am going to vomit.
