What do you think happened to Masao as he grew up?
Obviously at the end of the movie he was in high spirits as despite learning the truth about his mother, he still found companionship in his life and a parental figure in Kikujiro. However, what I'm wondering is whether he would have later on had difficulties coming to terms with the truth about his mother when he returned to his grandmother, perhaps fluctuating between acceptance and yearning.
Do you also think that later on in life he would have wanted to make contact with his mother and siblings or he would have completely moved on?
