[ Hibiya had opened his mouth to question that "why wouldn't I?", when she continued speaking, so he fell silent again, listening and watching her. Did he look that surprised...? He was initially more confused as to why she'd digest it, but he did exclaim with surprise, after all. And, she must have noticed that other expression of his, but -- well, it was already gone. At her smile and next question, he silently nodded with a small frown. ]

[ he was also nodding at the fact that she intended to listen to him read it, and so: ]

It's not that much, or that difficult! But, uh...

[ he begins reciting the lease in an overall deadpan tone, but he has good pronounciation, narraration and emphasis on (necessary?...) words. It seems he's fine with reading something out loud naturally, at least, when he's making a point to prove he's more mature (than she is)!? ]

...Basically, it looks like we've been kidnapped to live in this place?!

[ now he's sounding and obviously looking a lot more surprised, looking down at the paper with dismay. ]

And I have to go to school... and get a credit card...?! And this phone?! [ holding up said phone with more dismay, as if he can't believe the stated facts and that he's now holding one. To think he and Hiyori were just recently wanting to buy cell phones, before... and now, he suddenly, randomly has one. He could only dream of owning one before. ] ...And you get a new car?! Can you even drive, Auntie?!

[ she probably hasn't noticed, but he also read his own (random?) house number out loud, not hers! ]

[ (and why would she want to get him back, huh?! He is smarter than her, after all.) ]
