"We couldn't bear to be apart. So if Kizuki had lived, I'm sure we would have been together, loving each other, and gradually growing unhappy." Unhappy? Why's that?" With her fingers, Naoko combed her hair back several times. She had taken her barrette off, which made the hair fall over her face when she dropped her head forward. Because we would have had to pay the world back what we owed it," she said, raising her eyes to mine. "The pain of growing up. We didn't pay when we should have, so now the bills are due. Which is why Kizuki did what he did, and why I'm here. We were like kids who grew up naked on a desert island. If we got hungry, we'd just pick a banana; if we got lonely, we'd go to sleep in each other's arms. But that kind of thing doesn't last forever. We grew up fast and had to enter society. Which is why you were so important to us. You were the link connecting us with the outside world. We were struggling through you to fit in with the outside world as best we could. In the end, it didn't work, of course." I nodded. I wouldn't want you to think that we were using you, though. Kizuki really loved you. It just so happened that our connection with you was our first connection with anyone else. And it still is. Kizuki may be dead, but you are still my only link with the outside world. And just as Kizuki loved you, I love you. We never meant to hurt you, but we probably did; we probably ended up making a deep wound in your heart. It never occurred to us that anything like that might happen."
