As a youkai, why did Ah Yan want to help and take in Black Eye, and even personally tear up the scumbag in the end?
Before he died, Ah Yan was also a woman who gave everything for her husband and was betrayed, and empathy made Ah Yan can't bear to witness Him repeating his mistakes.
The first episode of "Youkai Shared House" tells the story of the legendary Ah Yan in the form of animation:
The story is from the "Tokaido Four Valleys Strange Talk", this "Four Valleys Strange Talk" is not four stories, but the place where the story takes place, which is a place called "Tokaido Four Valleys":

The monsters in the rental house listened to the story of Yu and all hugged her.
It wasn't until Ah Yan took the shot that the scumbag finally said what he really thought.
Punishing the scumbag for "cursing him to death" is Ah Yan's best trick.
Watching the scumbag man be frightened and run away in the wilderness is so cool!
Kuroku was completely awake. Although I lost my job and was kicked out of my home by my landlord for the sake of people who didn't deserve it, it was good that I could start all over again.
The story of the hand-torn scumbag man is popular with the whole people, and the first episode of "Monster Rental House" fully sets the tone of the cool drama, and the follow-up tearing scumbag plot can be expected indefinitely ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
