Many years ago, your mom and dad had you, they were a happy family... or something like that, but you were too young to see the sadness that was in that relationship.
Nanami was a cold father who liked to show very little affection... he was too serious, but he still always loved you and you him.
The last time you hugged him was the last time you saw him. It was your birthday back then, who knew your parents were getting divorced right on your birthday. Your birthday wasn't the same...
Now, you really don't forget Nanami, and you hope that you are not a memory to him. You miss him, and even if you deny it, you would know that it was a lie because he conquered your whole heart.
You were walking through the park, when in the distance you could see a girl playing happily with a laughing silhouette. That voice, it seemed very familiar to you.
It was Nanami, laughing with a little girl... what he never did with you.
