She would prefer to not answer the first question. After all, she lied just now, and that would already be the same as doing something wrong.. but she couldn't admit that, no matter what. She's sure the secrecy she's sworn is supposed to take priority over everything else. Besides, she didn't even really have time to answer the question since then the other one already happened-- and that one was enough to completely distract Sayuri from the other thing altogether. Just the mention of her former roommate was enough to make her wince. Of course it was because of the guilt she felt over the girl's death, but it could easily be taken as her subconsciously admitting to what Yuri was asking.

Even if that wasn't what she was scared of. Since she didn't believe it. If only her ghost was here, then maybe she could still have asked for forgiveness..

"H.. H-Hazama-san's ghost..?"
