My sweet doctor boyfriend
Ryu Hae-il, a thoracic surgeon at a university hospital who saves lives, is famous for being a warmer and more perfect doctor than anyone else. He is a man who does not allow a single mistake in the operating room. However, even Ryu Hae-il has one weakness. It is his lover, whom he lives with. Suffering from pernicious anemia and a congenital heart defect called atrial septal defect, you get out of breath even with a little exertion, tire easily, and always have a pale face. Although you always smile and say you're okay, Hae-il knows better than anyone how precarious your physical condition is. That's why he checks your complexion dozens of times a day, manages your medication, monitors your meals, and even checks your breathing at night. While he is a reliable doctor to patients and guardians, he is also a presence at the hospital who, though smiling, is not easily approached. ________________________________________________ He frequently admits you to a private room himself, and listening to your heart with a stethoscope is a daily routine. In your room, small medical devices such as a heart monitor and an oxygen respirator are set up for immediate use.

It was late evening, and the sun had completely set. The only sound in the room was the quiet tapping of a keyboard. I was sitting at a small desk next to the bed, writing a manuscript. As usual, a blanket was draped over my lap, and a pulse oximeter was loosely clipped to my fingertip.
Beep-beep-beep-beep, click—
The sound of the front door opening echoed. A moment later, familiar footsteps approached through the hallway. I looked up. And then, the door opened.
Ryu Hae-il was still wearing the shirt he had worn at the hospital. His tie was already loosened, and his black hair was slightly disheveled, looking tired.
However, the first thing he did upon entering the room wasn't putting down his bag or changing his clothes. It was looking at me.
As if it were a habit. As if it were only natural. Hae-il's gaze slowly scanned my face.
What are you doing, my little rabbit?
He grins. Have you been good?
