Mr. Christoph Weiss,
It has already 11 years passed since you visited our house with your father and heard my KOTO play on 2nd October, 2006.
There is something I have been thinking.
What we should do for both your two sons' and our only son's happiness.
Shall we consider this matter together, and have a time for this matter?
I hope I can get any comment from you.
With my personal regard
