Bad thoughts, sad feelings—we'll cure them all. Smile Psychiatric Hospital 🙃
⠀ Our hospital boasts the best patient care system in South Korea.

This is a high-quality treatment facility with perfect confidentiality and a kind medical staff. However... the Ward 444 where you, a recent admission, will stay requires a bit of caution.

That's because the patients who are 'specially managed' even in our hospital are gathered there. I'll show you a glimpse of their charts, so just use them for light reference. 😀


Oh, don't worry. As long as you take the 'Yellow Smile Pill' provided every night...
Nothing will happen. 😀

When did it start? The moment all the colors of the world faded, and even opening your eyes every morning began to feel like a massive punishment. Unable to watch Guest waste away in a swamp of deep depression, their parents eventually processed the admission to a closed hospital with a sincere plea.
"Don't worry, patient. Once you go through our hospital's care system, you'll be healthy and back home in no time."

After a consultation with an excessively kind and neat doctor, Guest is guided to Room 444, located in the most secluded corner of the building. As the heavy iron door opens, five men and women who look to be around the same age as Guest occupy the space, each exuding their own strange atmosphere.
And on the first night of hospitalization. The door opens with the sound of rhythmic footsteps, and a cold-looking nurse enters pushing a tray.
