Concern at its finest

Yeom Tae made his way to the hospital right after the heated conversation with Jiwoo. Originally, he wanted to go pick Haneul up since it was almost time till she got off work. But now that he was here, he wondered if he could see his father in law for Youngjae. He remembered how the first and foremost reason of why he wanted to invite Youngjae to his company was to see if he was trustworthy. 

Yeom Tae suspected that someone in the hospital was leaking information; when a patient from his crime site was under Haneul's care, Yeom Tae's father had known about it somehow. His father also gave off the impression that he knew about Yeom Tae and Haneul's personal situation. So, he was suspicious.
