Yoo Bum Ryeong from the future would immediately disappear if he killed himself from 1987.

To the people that are saying that Baek Yu-sub is the killer....
He and Hee-sub didn't know about the deaths. Yu-sub was in Seoul, participating in protests when the killing took place, when he was shot by police.

To the people who are watching from episode 1... .Rewatch ep.1 ending if you haven't seen the epilogue for it. I rewatched the series 3 times, and this is the first time i've seen that scene with KMS!! Also watch episode 3 epilogue carefully.

he did not only steal Lee Ju Yeongs ring, he also owned SoonAe's bow, which she wears all the time, the one that Kyung Ae wanted.

But you're right.. maybe he left it there for himself?

NVM i'm just becoming delusional for romantic crumbs.. It was just an hourglass, which could just symbolize turning back time. He removed the hourglass charm later and put it in the time travel machine.

I CAN ANSWER #3!!! That thing hanging on the time travelling car mirror is a necklace that has been previously hanging in Haejun's other car. As Ivy said, it's mostly used for decor/aesthetic purposes, but as many things, this necklace probably has a meaningful background. I theorize that he will give it to Yoon-young later, since she is wearing a necklace similar to that one in the photo I posted.

many people from the village visited Soon-ae, not just her classmates

No she framed her brother because he physically abused her all the time.

Also... Yoo Bom Ryeong died accidentally died, because he got involved by saving Soon-ae. Hae jun died the same way as Bom Ryeong. He probably got involved in the same type of incident, where he tried to save somebody, but died instead. Maybe Yoonyoung? The killer only kills womes and writes the notes for them, not the men, HJ also didn't have a matchbox, so the killer probably decided in the last minute to kill him since he couldn't kill his victim.

I don't think that the watch is just to prove that HJ is chairman Yoon's grandson. I think the watch is to show that two things that are the same, but from different time periods can exist at the same place. Maybe because the killer used a time machine to kill HJ and SoonAe

No she framed her brother because he physically abused her all the time.

I think the killer also time travels, thats why he is able to kill people after 30 years. and KMS probably knows that our leads also time travel, since she's a rat that likes to stalk and watch everybody's moves. Remember what she said to Baek Hee Sub in Episode 8?

"When do you think people fall into the gravest danger? The hope that you can correct all the wrongs. The delusion that you can make all your mistakes go away....... As you become intoxicated by this sweet, pathetic pipe dream, you realize at some point that..... no wrong in this world can be corrected. But by the time you realize that, you will already have been crushed by the wheel of fate."

I mean, any role in a kdrama would automatically make somebody be considered an actor. Every idol has a profile here because of some documentaries, or participation in game shows. doesn't really matter, but the fans are just overhyping the idol to the fact that he's overshadowing actual actors.

of course Kang MiRae is stale. the actress is stale in every drama

Since the time machine broke, YY and HJ stay in 1987, but they are from 2021. HJ died in 2022, while YY mom (Soon-ae) died in 2021 (present-time in KDRAMA).

ahh hyun bin and son yejin
