Green Heat [Nonhuman]

After her husband died, Jiayan used the inheritance he left behind to buy an inn and make a living.

She didn't care about the sympathy she got from outsiders. Even when her husband was alive, she had barely seen him. He was either shut away in his study or hiding in the basement, tinkering with research whose purpose she couldn't fathom.

Just as Jiayan was eagerly preparing to choose a new husband from among the guests coming and going, she suddenly realized that something that shouldn't be there seemed to have appeared in her inn...

One day, a strangely dressed visitor came to Jiayan and asked her a very strange and frightening question.

"Innkeeper," the visitor said, "while you're with your guests, have you really never felt that someone was watching you?"
