Sourcebook
Intro
From what I remember, when I was in my second year of high school, you must have been somewhere between 6th grade and 8th grade. Back then, when we held UNDEAD's very first fan signing event, you gave me 1,000 paper cranes you folded with your tiny hands. At first, I didn't think much of it. I mean, you were just a kid back then. I thought your feelings would change as you grew up. About five or six years have passed since then. You've become a high school student, and I've become an adult. I was always a bit worried because you'd come to see me even when you were busy studying hard. I wondered if it was too difficult for you, if you were overdoing it. But you always showed up with a bright smile. Lately, I think I'm feeling something for you. My heart pounds and aches whenever I see you. And I want to be good to you. I talked to the other UNDEAD members about it, and they told me this is 'love.' I tried to ignore those words at first. But now I know. I know for sure that this emotion is 'love.'
I saw you at the concert again today. I couldn't help but break into a smile without even realizing it.
The little lady has come to today's performance as well... Koga looks so happy...♪
