>brought out a list she had made earlier, handing it to him

....
Still a him?
But Pyotyr is a girl!
Otherwise YukiHana would not calla her Onee-san!!!!

>seeing a little girl hanging around the table, but decided to ignore her for now

Um...
YukiHana is bawling her eyes out, Tsukiya would probably be seen as heartless to ignore a crying little girl by the way
