There are spoilers, read with caution.

My prediction for the show ending is that Taesung at least tries to unalive Mido, and the ML ends up with the 2FL or ends himself.

Wait, wait, hear me out!

In episode 9, Mido and her producer/friend Oh Yeon Ju are talking in a bar. The producer says she has a movie adaptation. It's about a long-term couple where the girl cheats. Sound familiar? It turns out the boyfriend is not the one trying to k*ll her but…. And the story stops right there because Taesung walks in the door. It implies they are announcing who the killer is. He was probably watching her ignore his call right before he walked in. This is foreshadowing something, or they wouldn't have put it in.

Taesung is absolutely obsessed with Mido. This is OBSESSION! He stalks her for 3 whole months while she heals. I assume he follows her around a lot. He hires the film edit team she works for, and then he hounds her friend until she tells him where they are. Yeon Ju inferred he was interested in her. This behavior is obsessive.

In the scene where Mido tells him her secret about her father, he cries for her, but it's way too over the top for his character. I think he was acting to manipulate her again.

In the police station, Taesungs lawyer peer state Taesung unalived someone. Was that the whistleblower, the guy from the fire, or someone we don’t know about yet? This shows he's capable of it.

In the show poster only Mido and Namgung are in the foreground. Mido is the only one who looks at the viewer or out of the poster and not the person in the foreground.

Things I disagree with some viewers on.

The people who see Namgung having an emotional affair are the same viewers who work hard to excuse Mido of cheating and try to transfer the blame to the ML. He's not having an emotional affair. They are reaching around trying to find anything against him. I see no evidence at all of that view.

I don't recall any scenes where Taesung and Sua are together other than work before the attack happens.

One of the stupidest reasons was he caressed her face with that pencil. He did not lovingly move that pencil around on her face. He only turned her head with it to see the wound and not use his hand. THEN, they leave the "fix your wound" trope out, every KDrama uses that as a way to show one person's like for another.

Things I want to point out because some viewers missed it.

I believe the first and second kiss was SA because she pushed him away, and that means no, but I can argue myself out of it. Mido was fully aware of what was happening and did not get the hell out there. The lights were low, she was drunk, and he was kneeling and fully in her personal space. Long, longing stares and him talking in a low, husky voice. It would have been on like Donkey Kong if that knock didn't happen. I can see viewers all watching intensity, then some celebrating and others going WTH, she's a hussy!

He did not miss the snowfall anniversary, he wears a blue striped shirt and brown overcoat all day. The next scene after the pencil is a flashback showing him driving around the movie exec. Next, he's sitting in the park in a swing in the same clothes, waiting for her while it's snowing. Mido was kissing another dude. He probably called and waited for a very long time. Then he panicked, gathered her brothers, and went looking for her because she was absolutely supposed to be there. I bet he looked all night. It's probably a large part of her panic the next morning when she wakes up and realizes she missed it.

Mido started the pen recorder at the start of the fight on the bridge. When Namgung listens to it later, you can see the time length on the computer, 1 hour 19 minutes. Did he listen to everything they said during that whole night? Mido kept saying she did not mean what she said when trying to explain to Namgung, and I found that odd because she didn't say much right before the kiss. That means the bridge fight, taxi ride, elevator breaking and getting repaired, and kissing happened in that short time.

I am fully hate watching this show.
