Sorry about the dark screenshots, I use a blue light filter

You were transferred to Japan for school/job/travel and had just gotten to the house you were gonna stay in.

"Kage, whose there?"

"The transferee student from (home country)"

"Kage, don't use that mean tone with our guest."

"Sorry about him, he's a little upset at the moment. I'm Lin, and I assume your the transferee. Welcome to Japan!"

How do you respond?
(If you don't comment seriously I swear-)
