Okay so Lee Shinwoong has been suspicious this whole time only because he's been keeping an eye on Dong Baek, he doesn't truly trust him. And he is NOT the Eraser. Thank god I started to get super disappointed that they kept trying to hint that it was him but turns out it was just another occasion of them throwing us off the real one. So, is the Eraser actually Dong Baek or not? It's not quite clear because of the previews. He has in fact been the cause of murders though it seems because of the Shimbae incident. But I guess we'll have to see. I'm trying so hard to avoid spoilers from the webtoon.

I think it'll come up later.

Well is it Lee Shinwoong or Chun Kisoo? I'm low key hoping it's not Shinwoong cause they've been too obvious about the hints if it is him. Plus at the end of episode 11 they make it seem like its him by showing us the scar but I really don't think they'd just outright show us who the Eraser is after how much they've played with hiding his identity. It could/would make sense that its Kisoo though. He knew all about the murders because Sunmi shared with him the files as a teenager. He also met Jo Sungdong and knew of his connection to the murders as well. He could've erased his memory back then. The only thing that throws me off about this is the stature of the Eraser. He/She seems youngish, I mean they flew over the rooftop thing so swiftly. But anyways I feel like we're no closer that we were from last week so far.
If Kisoo is the Eraser how is related to Dongbaek?
Could be his father could not be?
What happened to the girl from Dongbaek's memory? (Will we ever get to know?)
Is Dongbaek losing his abilities or slowly killing himself by using them?

Oh no I agree they are making it obvious to be suspicious of the chief and istg if it ends up being him I’ll be mad.
But anyways, this is going to be a stretch but follow me on this. What if the reporter was dead before we actually think he died. Dongbaek could’ve killed him before he met with Sunmi (I can’t remember all of what happened before that scene so this is probably wrong, I’m just having fun with theories haha) and erased his two buddies memories. The scene where the eraser erases their memories could’ve happened long before both Dongbaek and Sunmi showed up. This also makes sense as to why the eraser didn’t harm them (though the two haven’t committed murder before so the eraser probably wouldn’t have harmed them regardless at that moment in time.)
What if (again this is a stretch here) Dongbaek is the eraser and he has more to his abilities that he’s leading on. Maybe he can read, erase, and manipulate memories? For right now say Dongbaek isn’t the eraser, then the eraser could potentially manipulate memories as well, aka alter/change them. Cause I mean I don’t understand how the eraser showed up behind Jaegyu in that scene if not. That memory wasn’t ever real, was it not something manipulated by the eraser.
Also every time we see someone’s memories we are seeing them from Dongbaek’s perspective (except some of Sunmi’s we saw through her reminiscing), he could essentially be tricking the audience as well. (It would be really freaking cool if that were the case, almost like he was using the ability on us.) anyways yes the kid saw the eraser in the sewer beneath them however, Dongbaek had already touched the kid long before then so if we wanted to implant some fake memory into him he could’ve.

I really really don’t think any of this could be true I just love talking to people about stuff that could happen that probably won’t. I’m just lost as to who it could actually be. Cause it has to be someone we’ve seen before you would think.
Again I find it weird that the writers keep making us doubt Dongbaek through other characters words. Ex. Bonggook in episode 10.

Though I really think the erase is screwing with both Dongbaek and Sunmi. I also find it kind of frustrating that the erase went from “killing people who deserved to die” to “I’m going to kill people around Dongbaek and Sunmi.” There’s just a weird correlation going in there, unless one of them has done something bad in the past. It’s just weird that the erase who taunted Jaegyu 20 years ago now suddenly wants to kill Dongbaek or Sunmi? Idk I’m sure it’ll all make sense soon.

Please tell me more about your theories!

Yeah the look on his face and the music was suspicious. I wasn't sure if I was misreading the scene or not, I couldn't tell.
I thought that maybe he erased the guy's memories of being beaten in the army because the guy seemed calmer when Dongbaek arrived with the money. But this could only happen IF Dongbaek was the Eraser. Or if Dongbaek gained the ability to erase memories himself and hasn't told anybody yet. But idk if this is likely to happen or not?
It may just be a way of saying Dongbaek is beginning to take this criminal more seriously. Like he's put his game face on. IDK. It was a weird scene.

The murders 20 years ago were committed by Jaegyu, he admitted to it. He then claims that the murders happening now (that are repeats of the murders 20 years ago) are NOT him. So, therefore that makes the CURRENT murderer the Eraser. Supposedly the Eraser was around 20 years ago though according to Jaegyu. However, if the Eraser messed with his memories there's no real way of knowing for sure if he was (so in a sense we can't rule out Dongbaek). After episode 10 I'm not sure it's Dongbaek that is the Eraser. I really feel like it may be the Chief Lee Shinwoong. They've been making him seem very suspicious from the beginning.

They also seem to like to play on the thought that Dongbaek isn't all GOOD (that we as viewers should be suspicious of him too). Like Bonggook (the male hacker who works under Sunmi) said in episode 10, that he felt off about Dongbaek. We also have to note that Dongbaek has been passing out a lot, in which he himself cannot remember what happens; for example the hospital scene where he walked around and disappeared for a while in the stairwell. He didn't remember doing that (or so he says) and no one can confirm exactly what he did. In a sense this could be a big game he's playing with everyone.
NOTE: This is a drama about a guy who can see people's memories but we have literally seen little to none of his own. We haven't really seen into his character's thinking much either. He's just as much a mystery as the Eraser. I find this intriguing. I think it would be a big twist if he were the Eraser. I'm not sure how exactly to get my point across here but I think it could be possibly that he is the Eraser. But I HONESTLY feel like the theory below is highly likely.

Another Theory of Mine:
I really feel like Dongbaek could possibly be the son of the Eraser, it would make sense since they both have supernatural abilities (and similar ones at that) and for the fact that Dongbaek cannot remember his childhood. In this theory I still think the Chief is the Eraser. There's no way it is someone who hasn't been introduced to us yet. There's no way this person knows as much as they do about Dongbaek and Sunmi if they aren't around them a decent amount. Those who were not around the hospital/Sunmi & Jaegyu at the end of episode 10 were the Chief and also Byun Youngsoo (the Senior Superintendent guy.) I find it crazy that he (the Eraser) figured out the switch of Dongbaek and Jaegyu though!

Anyone else have any theories?

Also did anyone see in the previews that Dongbaek claims that Sunmi's death would hurt him the most? I'm confused are they going to turn this into a romance or are the two brother and sister? (The Eraser could've erased Sunmi's memories of a brother, & we all know Dongbaek isn't Dongbaek's real name and he doesn't remember his childhood, kinda a stretch.) Or is this hinting at something else?

Could be!

I agree!

Oh I know about the two guys having their memories erased. But I was wondering if maybe one of them erased the others memories and made it seem like their was a third person there that did it, it’s a stretch but we really can’t trust anyone’s memories at this point.

I mainly think it’s the chief because of everything you said. He also had that file on Dongbaek and just seems so sus. But I also wondered if it were possible that the erase was someone close to Dongbaek. Maybe one of the two guys that is always with him. So you know they both had their memories erased by the eraser but one of them could also easily be the eraser too. They seem much more like a stretch to be the criminal. So I’m leaning closer to the chief. Unless somehow Dongbaek has been tricking us the entire time. Which in my opinion would be genius. But I don’t see that happening either. I think it would be cool if he like was the son of the eraser. And that’s how he got his ability. Or he is the eraser somehow, we still have to remember he’s been passing out at times and not remembering things. (This could also be a case of the eraser visiting him too.) anyways I’ll stop my rambling. I am leaning towards the chief the most.

I'm still wondering who the Eraser is. Is it Chief Lee Shinwoong, cause I mean I feel like they are pushing it to be him from how sketch he's been acting? He seems to fit the age requirement. But again I will kind of be disappointed if it is him because they are making it a bit obvious if so. Anyone else think it's him or someone else? I have a few other I'm suspicious of too.

OMG really? I would've thought Minho would've got the male lead position.

Yeah I do agree she got annoying there for a bit but after finding out the case is related to her I just let it go. I do think the two Main characters personalities clash but maybe that's intentional?

Istg if I get SML Dohwan I may die. :.(

I think it makes sense that she's started to become a bit reckless, I mean this crime is related to her. It just wouldn't really make sense for her to act the way she usually does when this case they are working on clearly connects to her past.

So far I think it's only been mentioned once, we haven't been shown too much into Dongbaek's life yet. I'm sure it'll play a bigger role eventually though.

No his superpower is to just see their memories through touch. Doesn't have to be just fingerprints.

So does the whole Red Brick thing even happen in the drama? Can someone tell me?

I think some parts of the drama took too long to get through but then at the same time the last 2 full episodes were definitely rushed. I think if they cut down some of the scenes in the middle the last 2 episodes would've went together better. The romance (although I LOVED it) overshadowed some things near the end too. Like we don't get a glance at the writer or why they keep writing the same characters over and over again, you'd think the writer would at least change their names. We don't get to know why Dried Squid or Kyung's brother were already aware from the beginning, why Soohyang was introduced so late into the story when she really served no purpose to Namjoo & Jooda's storyline, especially while being aware of herself? While some things rather big were left with no resolution I am happy that Haru and Danoh got somewhat of a happy-ish ending (though still tragic nonetheless) and that Kyung realized he was an ass.

Yang Sejong and Woo Dohwan in a drama together!! Lets hope the plot isn't trash because I love those two!
