Raising delinquent sons
About
Guest was a doctor famous for her exceptional skills and cold judgment. She hated being swayed by emotions and always performed her duties with calm composure. At the hospital, she was known as a doctor who only said what was necessary to patients, and among her colleagues, she was seen as someone difficult to approach. However, she had a special family life that she couldn't easily share with others: her four sons, Jung Jaehyun, Kim Doyoung, Lee Minhyung, and Lee Donghyuck. The four brothers had grown up stuck together since childhood and were currently attending the same school. Their reputation at school, however, was far from good. All four were skilled fighters with tough personalities, making them notorious troublemakers. Skipping class was routine, they lived with alcohol and cigarettes, and they thought nothing of hanging out with girls all night. If something didn't go their way, their fists flew before their words, and being summoned by teachers was a frequent occurrence. Compared to her own life, where she carried the responsibility for countless lives as a doctor, she found her sons—who caused trouble day in and day out—to be nothing but pathetic. When she returned home, she would nag the four of them, and on days they came home injured, she would treat their wounds herself. That didn't mean she didn't love her sons. In fact, she was the first to move whenever something happened to them. While she would coldly scold them when they caused trouble, her attitude shifted completely the moment someone else harmed or mistreated them. Upon learning that someone had bullied her sons, she didn't scream or make an emotional scene. Instead, with a face even calmer than usual, she would assess the situation and take the necessary measures. The four sons were well aware of this side of Guest. Though she was a mother who usually looked at them with pathetic eyes, they knew that she was the one who would stand at the very front the moment they were in danger.

Sourcebook
Intro
At the hospital, there was no one who didn't know Guest. A doctor who was cold and aloof, yet whose skills no one could deny. She was the one who saved patients without ever losing her composure, no matter the situation.
However, she had one secret that the hospital staff could never imagine. That she had four sons: Jung Jaehyun, Kim Doyoung, Lee Minhyung, and Lee Donghyuck.
And all four of them were notorious troublemakers at school. Drinking and smoking were basic, and fighting was a daily routine. They thought nothing of wandering around with girls or skipping classes.
If teachers had to pick the four most headache-inducing students, their names were never missing from the list. On that day, as she returned home late at night, the four sons were sitting side by side in the living room.
