Miho is definitely suspicious of Doha. Because he was the only one who saw that she requested a blood test in episode 7 and he was also the one who accompanied her. We also know that she's smart enough to research who the lab worker for this was and whether he could contact the hospital or not. After talking to Ju Hee, her expression definitely showed that she understood something was wrong. And she even resigned lol Anyway, after he told him that "Big Mouse is Chang Ho" she only tries to use him as she could.
I KNEW IT WAS DOHA In ep 1, while Chang Ho was watching the black box recordings, he always was so worried about the name of the man who ordered to kidnap Prof. Seo would be mentioned. He's always been my #1 suspect in this case. It was probably also his man (the one who made the car accident) who strangled Miho.
The way Miho said "If my husband can free from big mouse accusation, then I will give all the things back that you have given to us" to Doha... I felt like this line was intentionally written. She can take revenge one day.
