Don't worry. I was under the influence, but Kasumi-san herself was not; she was very kind and understanding with me, even though I was terribly awkward about my new feelings and...speaking to someone other than Saul-san. It possibly happened before I'd even met you.

And I did meet her several times afterward. We talked about different things and I came to truly enjoy her company. It wasn't long at all before I started looking forward to seeing her; she was one of my first friends.
