This is a BL AU. Scene : Beginning of episode 3. Yang Jae-won has been tirelessly working every second in the OR and ER ever since the second he joined the trauma center with the guidance of Dr.Baek Kang-hyuk. It was raining and thundering as they both walked to their shared quarters in the hospital building. Yang Jae-won dragged himself like a zombie, groaning as Baek Kang-hyuk watched him from behind, curious. They both entered their quarters. Yang Jae-won got on top of the bunk bed, whilst still wearing the surgical scrubs. Baek Kang-hyuk, took off his white cloak and placed it on the hanger "You a zombie?" He said as he observed Yang Jae-won finally resting instead of the endless groaning. He stared a few more minutes before calling out "Anus!" Jae-won quickly sat up on the bed, his head hitting the ceiling very badly. "yes Dr.baek..?" He said, tired "You gonna Crack open your skull?" Dr.Baek looked at him, he sighed, laying on the bottom bunk before continuing "Get down and sleep with me"
