This video is a 10+ year video growth record of a daughter shot by a man living in Tokyo. "My dad isn't my real dad. Before I became a junior high school student, my mom remarried, and then he became my dad. When I wrote this homework essay, I asked my dad about my treasure. Then, my dad answered, "My treasure is Ruka." But, more than my real dad, I... I love my dad." This is a speech that Ruka gave at a middle school class observation. The theme of the speech was "My Treasure." I was so happy that I couldn't help but cry. Ruka and I aren't strictly blood-related. We've just spent time together since we were little. I've watched Ruka grow up very, very closely. I love Ruka, and Ruka loves me too. More than a real family. We take baths together every day and sleep in the same futon. We hug and kiss too. I think I first had sex when I was in junior high school. I know where Ruka feels good, and Ruka knows too. My sperm hasn't flowed into Ruka's body. That's why, even later, I have to give Ruka a lot of my dad's sperm. I think that's my role as a dad. Ruka, I like you. I love you. I love you. Now, say you like Dad. One more time. Say you like Dad. One more time, one more time, one more time...
