To save him, Shinjushin decides to perform a surgery that goes beyond the realm of conventional medicine.

In episode 2, the atmosphere changes drastically as the 'brain change surgery' makes its full appearance.

 

As Momo's behavior and facial expressions have changed since the surgery, various interpretations are emerging among viewers.

There are also continuing reactions that it is not just a simple medical drama, but a work that deals with identity, desire, and the twists of relationships.
