Only me can maintain the roof with wheat.

This roof is lined with wheat, but I am the only person who can do this work.
It is a traditional technique that has existed for a long time, so I will do it as long as I live.
In my case, I was self-taught while watching the work of a craftsman who maintained the roof before.
It took me ten years to learn the technology, but now I can perform normal maintenance.
If you are interested in the roof, I would be glad if I could talk to you when you come here.
