A new member of 221C, Mrs. Hudson originally heard that a cute girl was coming as a guest. She promised that this would be the happiest thing for her since Sherlock's "resurrection". After all, she is old and it is not a small thing to be "tortured" by Sherlock and Watson. After seeing the real person, Mrs. Hudson could only say hehe.
Why does this 16-year-old girl have the high-functioning anti-social personality of Sherlock? (╯‵□′)╯┻━┻But after Watson "marries" out (?), It will be a good thing to have someone who can control Sherlock.
This is a sweet nurturing story. The heroine is both highly intelligent and anti-social. It is a bit of a child-bride style sweet story. It may become too sweet in the future, and I will not be held responsible for the sweetness.
