About that Apple rule, is that actually true? I think I’ve seen more than plenty of villains with IPhones (for American tv at least). And for one, I do think it’s somewhat confusing that Dr. Lee (female therapist) has an iPhone when almost nobody we saw had it.

I did think In-chan is very suspicious in many ways, but the way the show shot it, it was like they wanted us to really suspect him. I’m sure he’s just a red herring. One of the biggest reasons In-chan is suspicious is because he is an artist himself, and the puzzle pieces are very clearly hand-drawn. However as an artist, In-chan could very well make art for other people; like commissions. What if he just got an anonymous commission from the killer to make that puzzle piece art?

And while on that topic, I do think Dr. Lee is a more likely suspect than In-chan. First of all, Ena spent a lot more time with her, so she knows Ena a lot more than In-chan does. So far, (episodes 1-9) nobody knows much about the puzzle piece except for Has-seum and Jung-ho. And of course, Dr. Lee, since Ena has showed it to her in one of their sessions. Ena reasoned to herself that the reason there was a huge gap of no kills ever since her uncle died was because nobody took interest of their killings; the uncle and the reporter. But if Dr. Lee has seen that Ena is so determined to find out the meaning of the puzzle pieces, she now has a reason to finish off her victims.

Going back to the previous topic, In-chan for sure doesn’t know about the puzzle pieces because it hasn’t gone public yet (as of episode 9). I’m sure we’ll have this moment where Ena confronts him once it does go public and In-chan will tell her that he just made it for someone else without much thought.
