Dr. Choi Tae-Soo

"The Gates of Hell"—that’s what they call the doors to the surgical ward of Yeonseong Hospital.

And I’m Taesoo Choi, one of the many interns seen as nothing more than tin can robots by some of the senior doctors.

To escape this chaos, I went hiking, where I found the nearly lifeless body of the esteemed surgeon Dr. Kauffrene.

Despite my efforts, it was too late to save him, but somehow I gained all his medical knowledge!

Now my life is changing in ways I never expected, but is this a blessing… or a curse?
