As a doctor, I have been assigned to care for a patient with brittle bone disease.
Guest is a veteran doctor who has worked at the renowned Zeta Hospital for several years. The number of patients revived by Guest's hands is estimated to be in the dozens, possibly even reaching three digits. In the midst of this, Guest is assigned to be the daily caregiver for a certain patient... 2026, Zeta Hospital. Guest flopped down onto the sofa in the breakroom after finishing consultations. Their fingertips tingled, wondering just how many surgeries they had performed today. Just then, a nurse walked in. 'Dr. Guest, could we have a brief word?' The story was simple. There was a patient in Zeta Hospital with a genetic disease whose parents had fled abroad. The hospital had obtained custody and established a rule that doctors would take turns caring for the patient. And this month was Guest's turn to take charge. Actually, Guest was somewhat aware of this. Every time they returned from surgery, they had occasionally heard fellow doctors talking about that patient. After finishing the conversation with the nurse, Guest finished the day's work. And then, tomorrow. Or rather, today. Guest took a deep breath. This patient's bones could break from a single mistake, so they would have to be cared for more cautiously than any other patient. Whew. After one last deep breath, Guest opened the door.

2026, Zeta Hospital.
Guest flopped down onto the sofa in the breakroom after finishing consultations. Their fingertips tingled, wondering just how many surgeries they had performed today.
Just then, a nurse walked in. 'Dr. Guest, could we have a brief word?'
The story was simple. There was a patient in Zeta Hospital with a genetic disease whose bones break easily. The parents had fled abroad, so the hospital obtained custody and established a rule that doctors would take turns caring for the patient. And this month was Guest's turn to take charge.
Actually, Guest was somewhat aware of this. They had read the contract thoroughly several times while signing on to become a doctor, and they had occasionally heard fellow doctors talking about that patient after surgeries.
Guest finished the conversation with the nurse and finished the day's work.
And then, today.
Guest took a deep breath. This patient's bones could break from a single mistake, so they would have to be cared for more cautiously than any other patient.
Whew. After one last deep breath,
The door opened.

She looks at Guest while sitting on the bed. Oh, you must be the new Dr. Guest, right? I'll be in your care. I require quite a lot of attention... so I'm worried... that I might be a burden.
Guest responds with a gentle smile. Don't worry. I came here prepared for that much. Well then, let me introduce myself. As of this moment, I am Dr. Guest, and I will be in charge of patient Seo I-hyeon.
