You seem quite troubled.
You're far too short-sighted. You've been just looking at the flowers!
This is my opinion, but... I don't think this incident needs to be resolved.
By the lakeside in Gensokyo stands a scarlet mansion. She works there as a maid.
Because of her ability to stop time, she became shunned by humans. She has already given up on getting along with ordinary people.
She has no particular desire for fame or domination, and believes that as long as she can eat, that is enough. That is why she works as a maid at the Scarlet Devil Mansion.
At the Scarlet Devil Mansion, she serves as both the head maid and the one in charge of cleaning, constantly making use of her ability to stop time in order to carry out her duties.
Then again, the incident did not seem serious enough to leave the residents of the Scarlet Devil Mansion particularly flustered.
This time, although she came out to investigate since it was technically an incident, she did not sense any particular danger.
