Mashuu is a sensitive child. He's more mature and tends to think differently than other kids, so his romance can't be just anyone around his age. He might think of Satoko as an older friend or practically a substitute for his mother at first, but it changed as he grew up. It's okay for Mashuu to be a bit vague about his feeling toward Satoko. Even if they can't be together at the end, I believe Satoko will always be important to him. It's Satoko I'm worried about. She also thinks a lot and is too cautious of prejudices about normal relationship. It'll be hard for her to open up to anyone after Mashuu
