wait nvm someone already said it

New theory after ep 6:

PSO is the missing twin from the orphanage and kidnapper is the other twin

 mahiba:

1- I think the FL's mom and ML's dad have or have had an affair. Or at the very very least he has a big crush on her. That would explain why ML's mom, who is shown as very calm and self controlled, cannot even hide her contempt for FL's mom. 


2- I saw someone mention that the psychiatrist (2 ML) likes seafood, like the real Sae On. That would mean that the childhood story 2 ML told was a lie, or if not a total lie, he was the one in the mask? (BTW the use of the mask when they were kids is supposed to make us think of The Man in The Iron Mask right? ) Anyway, then who was the real orphan then? Sae On? He did seem a tiny bit interested in the name of that orphanage. 


3- I also wonder why the kidnapper keeps calling FL unnie, instead of noona... 

I did doubt the 2nd male lead when he told his story. It feels like when liars try to share stories of their atrocities but don't wanna get shunned, they resort to making themselves victims in the story.

I'll back you up on that one.

Okay, there are some theories I’m cooking. I think 2ML  knows real PSE is the murderer in the past and thinks ML is real PSE. I think he is behind the funeral flowers and the message left at the house, I dont think however he is involved in the kidnapping as it looks like he really wants to protect HHJ and dont look like he knows she’s married to PSE. I think kidnapper (real PSE - the line saying he wants everything even PSE perfume makes me think this)  is using the house at different times and kidnapper found the message 2ML left the day before and sent the message to HHJ. But idk… I guess from now on I’ll let the theories go and just enjoy the ride.

I think one of the boys who went missing from the orphanage, "Park Minwoo" (they didn't show us his picture), is the current Baek Saeon.

 Grandpa Baek tried to kill him by drowning because he found out that the real Baek Saeon killed the other children, but the guy who owns the fish shop rescued him.

 Ji Sangwu might be one of the twins. He also found out that the real Baek Saeon killed the children, and Grandpa Baek tried to drown him. That's what the current Baek Saeon saw. (Ji Sangwu also remembered the design on the ring)

 Park Do Jae might be Ji Sangwu's twin, and he might think that Ji Sangwu is dead and that the real Saeun killed him, just like the other children. However, Park Do Jae doesn’t know that the current Baek Saeun is not the real Saeun. That's why he's taking revenge, because he thinks that Saeun killed his twin brother.

 On the other hand, Ji Sangwu is trying to find his twin through the project he's currently working on. Meanwhile, the psychopath (the real Baek Saeun) is working with Park Do Jae because both of their goals are to hurt the current Baek Saeun.

The big bad guy is 2ML= Sang U= psychiatrist = one of the twins.
