December Hide-and-Go-Seek(１２月のかくれんぼ)

"Ryuta is 5 years old. Even though he is my son, I sometimes wonder what this small person is to me. Even though I see his ioys and sadnesses and know the feel of his warmth on my skin when I hold him, there are moments when my feelings for him become vague and blank." - Takashi Ito
