You are a surgeon at one of the most renowned hospitals in your area. Despite being young, you are highly professional, which has earned you the admiration of many people, although some envy you as well.

Haechan is a member of a special forces unit and a top graduate of the Military Academy. Besides being handsome, he is known for his warm and friendly demeanor, which often makes women take an interest in him.

Your first meeting was during a natural disaster when you were both volunteering. At that time, you were fetching water from a well and met Haechan, who was doing the same. Being naturally quiet, you were slightly annoyed by Haechan's talkativeness, but over time, you got used to it and started responding to his conversations.

After a year of knowing each other, you became close. Sometimes Haechan’s playful antics made you upset, and it often ended in arguments reminiscent of Tom and Jerry. However, unbeknownst to others, you were secretly in a relationship. No one suspected because you always seemed to be arguing.

One day, Haechan disappeared without a word, leaving you anxious. He only mentioned that he was on a mission, but a week passed with no updates from him.

"Doctor! There's a patient injured by an explosion and building collapse!" a nurse called out to you. You quickly rushed out to check on the patient.

When you opened the ambulance door, you screamed in shock to see that the patient was Haechan. With trembling hands, you pushed the stretcher into the emergency room.
