I think only the doctor part is not shown in the manhua. The one where he had to move though the place to reach drunk daejoon, i think it's n the manhua! Also i have hread the novel, i could as well be confusing both but i remember reading that drunk scenario.
They didn’t put this in the Manhua but it already happened…
When they first met, Sihyun knew about the dispute between Hwain and Taekang.
Daejun noticed Sihyun tapping the armrest of the sofa which Hajin does when he is thinking or lost in thoughts.
He also noticed how Sihyun smoked, holding the cigarette between his ring and middle finger, but suddenly started coughing with teary eyes as if it was his first time.
The role that Sihyun played in the drama Blue Thorn was a loan shark, and the way he acted was very similar to Hajin.
Sihyun looked at the documents related to his past like they were someone else’s.
Everyone (coworkers and fans too) noticed the change in his behavior before and after the accident.
Till here it was shown in the manhwa. Daejun had half confirmed, was confused, and thought that he was going crazy. So he dug for some more information on Sihyun.
The Drunk call incident- Daejun went drinking with 2 of his subordinates, after they left, he called Sihyun. It was the place Hajin and Daejun were regulars and they always used the same room. Sihyun told Daejun it took him a lot of time to find the room. After entering, he was surprised to find Daejun drunk (he was actually sane enough to know what was happening in his surrounding). Sihyun asked who he had been drinking with, hearing Daejun’s answer he nodded his head- showing Sihyun knew those two. Later he said something that he had once said as Hajin, that He wanted to go on a long trip (or retire, I’m not sure)once everything is over, for Hajin it was the dispute with Taekang and for Sihyun it was his idol life. After Sihyun leaves, Daejun gets up and goes to the security room to check the CCTV camera and saw that Sihyun didn’t take much time to reach the room as if he already knew where he was supposed to go.
Daejun also threatened told the doctor to spill what he knew about Sihyun’s accident. He tells him that he was the one to confirm Sihyun’s death. Rigor mortis ( stiffening up of one's body after death) had already started, His leg was twisted to the point his bone was seen, and had a severe head injury. After waking up miraculously, He didn’t know who he was but he kept asking for the man who was with him. ( the People involved in the accident were only Sihyun, Hajin, and Daejun i.e., there was no one with ‘Sihyun’)
This made Daejun conclude that Hajin was in Sihyun’s body
