As of Episode 03
- The CEO. He wants to drop him because he's becoming a headache. He's willing to risk the drop in share prices because he expected it to be closed fast. Unfortunately for him, there's a fierce attorney who's prolonging it.
- The Manager. Out of all the people around him, he's probably the one who's most angry since he's the one who has to endure everything.
- One of the staff. Three of them did say they want to kill him and were holding pointed objects.
- The father(?) of the prosecutor. As he said, their job is to pick a suspect and force them to confess regardless if the confession is true or not. He probably heard the comments of the disgruntled staff and so he set the ML up.
- The father of the ex-girlfriend. They haven't shown him yet but since they're wealthy, her father probably hated that they were dating. He was probably the reason why they broke up.
- That angry band member, the drummer IIRC. The victim didn't struggle, as the police said, the victim knew the suspect. And since the victim is also intoxicated, more reason he wouldn't think the suspect would actually stab him.
Why I think the ex-gf is not the suspect:
- She was paying attention to the case.
- She studied the profile of the prosecutor.
- She met the prosecutor pretending to be interested in him, but she was actually fishing for information at the same time planting doubt and leading him to other possible scenarios.
However, I suspect that she knows something. She probably knew who the suspect was but she's too afraid to share the information with anyone because she'll get dragged into it.
Again, only up to E03 as of the time of this writing.
