Xiao Kui's constitution is the main reason. Since her birth, her constitution has contained special attributes. In the story, she touched the box with the hand of an ape, and the box opened itself. Then she hooked up with April 1 ST, and April 1 ST's little finger couldn't move anymore. She bumped into April 1st's shoulder, and the window that Junxun's shoulder touched was broken, causing Junxun to fall from the third floor.

Xiao Kui will bring misfortune to others, not the object she chooses, but the people and things she contacts. This is an attribute that has existed in the depths of the soul since birth. If her parents were also affected, she would not be born, so Kwai's parents would not be affected by this constitution. In the cartoon 1 18, it is mentioned that she went to the house next door to pick up the ball when she was a child, and a fire broke out the next day. Her grandmother also died of sunflowers. So if she cooks, it will bring bad luck to others. Only Kwai's parents and Dodo Meggie, who has exorcism constitution, can eat it, and it is not affected. Jun Xun, who got a lot of beautiful blood, hasn't eaten the rice cooked by Kwai. I wonder if Jun Xun, who got the exorcism effect the day after tomorrow, is still affected.

Just like this, contact with others will bring misfortune to each other, and the closer you get to her, the more it will hurt each other's life. Therefore, she has always avoided contact with others, using various reasons to prevaricate others, what technology is not good, and she can't buy things together when she has something at home. In the cartoon 1 18, she told Jun Xun about her physique, and the end of the second animation is also the animation of this plot, which is the way for Jun Xun to get out of this situation.
