Dong Go-yun is a proctologist at the same university hospital, a steady and good-humored presence who becomes one of Da-eun's closest sources of support. Initially defined by his easygoing competence and his slightly comic specialty, he reveals a thoughtful and caring nature as he grows closer to Da-eun and comes to understand the emotional demands of her work on the psychiatric ward.
As the season progresses, Go-yun offers Da-eun warmth, patience, and a listening ear away from the pressures of caregiving. The drama uses his character to show that emotional support can come quietly and without grand gestures, and that being present for someone is itself a meaningful act. His relationship with Da-eun develops gently, in keeping with the show's understated tone.
Go-yun's arc reinforces the series' broader message about compassion: caring for others, whether patients or the people we love, is a practice that asks for honesty and steadiness. By the end he stands as a reassuring counterpart to Da-eun, part of the small circle that helps her stay grounded.
