Well, let me start by saying that the CP of this article is relatively unclear. It is probably Kyrgyzstan lacquer & Kyrgyzstan silver, which contains a small amount of platinum. Please don't pinch the CP... Because the author is a fraternity party.
There shouldn't be a clear description about Yoshikuri or Yoshiun. The three of them are like family & friends. Please don't think Uncle Ji is a scumbag. In fact, this somewhat confusing CP situation is caused by the author's own entanglement. Please don't attack CP~\(≧▽≦)/~
