Zero looked at Isaac, who stood there waiting for Zero to get up, for a few moments before he made an awkward smile as he stood up and gave place to Isaac.
"Sorry, I didn't know that these girls had company," he said before looking at the three girls who were making a confused expression. He then smiled before speaking,"well, I have urgent work to attend to. Let's meet again if fate allows us to," and then bid them goodbye waving his hand as he walked to the counter where he paid the bill.
"Who was he?" Isaac sat as he kept looking at Zero with a narrowed expression and then Eliza answered with an awkward smile, hurriedly before anyone else could speak,"that was… Zero. He said that we looked like someone he knew and began talking with us. He was a bit funny, so we let him sit with us for the time being while we waited for you." Her eyes were concentrated on Isaac as she tried to understand more about the brother of the Rose sisters.
