I can't forget

CIPA

In episode 11, Wheein said that she has no pain and is analgesic.

Analgesia is called CIPA (congenital insensitivity to pain with anhidrosis).

It is a congenital disease that makes it impossible to feel pain and temperature (cold, hot).

The reason why Wheein doesn't feel pain when she cuts her hand on a piece of glass in episode 4

Why can't I feel the temperature when I'm being examined in episode 6?

In episode 11, I spilled ramen soup, but why can't I feel the heat or the pain?

That's because Wheein is CIPA.

Ah, I'm uploading this in the hopes that it will be a little more helpful for those who are looking for a small piece!
