He will be in Season 2 because we already know the story. Moving is based on comics(webtoons) and next Comic after Moving is "Bridge" in which that Time Stopper kid as huge role, actually he is not kid anymore. You can see he in post credit scene of Light Shop dramas which set in same universe.
Moving season 2 Most likely will cover webtoons Bridge and Hidden.

I am also not sure about how much Hyunmin love her the question is why he forgot her in after life and after that while everyone other person in coma remembered their significant others. Kang Full never actually gave the reason like I said. he left for audiance interpretation. So if their love was real then was it the suicide which cut of his memories of her?

Seol hyun wants that interpretation. Thats one way to say his haunting him ( Haunting means a ghost is attached to you and following you) as her ghost now attached to him, the problem is a ghost who doesn't move on to afterlife becomes resentful. Yes she is not actually try to harm him but she is one resentful ghost now and will get corrupt eventually. The movement any Grim Reaper(like Detective become one now) sees her she is done for, because they won't let her be in living world.
Grim reapers make sure that there are no ghost in living world and everyone who has competed their lifetime is dead.
There chance that Hyunmin was also supposed to die but Ji Young being there changes his fate which is a rare occurrence in Kang Full's universe.

I enjoyed it alot until episode 7, I don't know what his plan was. It was never going to succeed.

Because that's afterlife and they are not strangers anymore. Afterlife supposed to be place where people who died an unfortunate death before fullfill their life, live a normal life. So now all of them actually living as a normal citizens.
Strangers and Outsiders are both invisible to the actual citizens from what I can understand. Like all the Hyunjus classmates are miscarriage babies who are living here. They never see Hyunju or All the bus passngers never saw Hyunmin or Ji Young . Strangers are seems to be trapped in that particular area lighthouse alley area.

Yes, She is haunting him.It's a sad ending for them. As Hyugmin completely forgot about Jin Young and Jin Young turned resentful and refused to go in afterlife and now haunting Hyunmin.
It's clear that Hyunmin never remembered Jin Young even in the Coma state, he just pretend to so he can get out of there and was desperate for life. Kang Full (Writer) never gave the clear reason why though because of that it's for audiance interpretation like why he didn't remember. Is it because she took her own like which is a great sin and she is getting punished for it? or Maybe Hyunmin never actually loved her that much to actually remember her?

Most probably either whole family or someone from family is getting mind controlled to give the details about FL. There must be some trigger to activate them.

It's a theory yes but it can be considered as misdirect. I get all your points but there are counter points firstly we never saw kids body or his name in funeral home where all the bodies are stored from accident. second if he really has died why he is not in after life ( like all the other ghosts/outsiders) where he can actually meet the highschool student himself and thank him without needing to visit ICU or no need for Park Bo Young. Also none of the ghosts ever waited outside ICU, all of them entered Directly. Whenever Park Bo Young meets ghosts/outsiders she always tells them to seek light as we see that she told every ghost to sent strangers towards light, she didn't say that to kid. Only basketball appaers in after life after Park Bo Young places ball by patients side. At the end when we see all the dead people are living in afterlife we never see that kid living there. Kid has highest chance of survival as highschool student wrapped the ball around him as soon as possible so he float above water while everyone else was drowning for way longer. To me it was a misdirect that Park Bo Young talks to him because she is our main nurse character. There is also another thing that basketball was physically there as she got that from kid if he is ghost then normal people saw that basketball flying in hospital? is thats what everyone was seeing? For kid being there even if it was just 4th day I think,? So isn't it possible that he was just discharged and wanted to give that ball before going home?

Disney plus. It's their original show.

He name is Young Tak, He is from Timing webtoon the prequel to Moving. He makes cameo in Moving drama also in episode 16.
I think he and detective is most probably have huge role in Moving Season 2.

Yes, there are multiple grim reapers. Both alive ones(like Detective) who exists in real life and dead one who exists in afterlife(Shop owners).
Spoiler if you ever read Timing. ( From where the Young Tak the time stopper is) You will see fight between two grim reapers. Where other grim reaper is behind all the killings. Actually detective also have huge role in Timing as he goes against other reaper.
Also there are Shamans, Some are powerful enough to scare grim reapers also.
There are also more time manipultors exists, it's good thing that they all are good guys in timing. There is Time Stopper that we met, Time Rewinder, Precognitior and I don't know what's last one is called but she also basically powerful shaman.

For the first question it's took some time for Ghosts (Outsiders) to understand what actually going on as well and that red shoes lady wasn't trying to scare that highschool girl is just that at the movement she can't control it, she was just trying to have conversation, it just that audience misunderstood at that time as there was no context. After Park Bo Young told her to seek light she understood wants needs to be done. And at the end that lady tells bus driver to find that highschool girl and tell her about light.
As for Detective I can give you his whole timeline.
1. Detective starts working on that old man's sucide case.
2. He sees that there is Noodles order and suspects Noodle shop owner as murderer.
3. Detective keeps tabs on Noodles shop owner but one day he sees him chasing a women with his scooter.
4. Detective thinks that Noodle shop owner is trying to commit another murder so he is chasing him and he catches him in middle of the road.
5. Noodle shop owner suprised that detective can see the Ghost lady as he should not be able to.
We learn that Noodle Shop owner is alive and have job as grim reaper who sent resentful ghosts to afterlife.
6. Now when they are fighting both get hit by a car and noodle shop owner protects detective resulting in his death and detective goes into coma.
7. Now when after finding light detective comes out of coma and in real world. He is alive but he learns that Noodle shop owner died.
8. Detective visits Noodle shop to meet with the Owners ghost. He meets with him and thanks for saving his life.
9. Now that Noodle shop owner is dead he needs to move on to afterlife but his job as grim reaper needs to be done by someone. so He gives his powers to Detective and responsibility to hunt resentful ghosts.
Detectives eyes have power of reaper in real world as resentful ghosts exists in real world who doesn't want go to after life or has not moved on yet.

still have questions? It was straight forward in show.

I don't get what you are saying? what parts weren't link correctly? Everything makes sense in correct order.

WTF did I just watched? It did have some laughs but I just didn't get the whole point or Cops letting them go, I get that cop manipulate them to kill the drug lord but they also have killed alot of other people. So why let them go at the end?
And what's the point of that highschool girls revenge storyline? Younger brother said he will kill him thinking he is basically guy but next time we see the gir she is basically living with them, maybe she started liking younger brother I think and moved on.

Because he never questioned how she is able to talk or how he didn't hesitate to leave her behind.
the biggest hint is that Ji young her self said that he didn't remember him as she also suspected him to react differently.
As for little boy, He is pretty much alive and we didn't see him much because he survived and never went to coma so don't need to see him. He just showed up to thank that highschool kid who wrapped ball around him which saved him.

Bus driver went to afterlife, In the end scene you see him driving the bus in afterlife he is doing the same job. He is moved on. He is not remorseful.

It's written by same writer and takes place in same Universe. The drama also written by same comic writer . There is connection because the next story after Moving in webtoon is "Bridge". Which includes characters from webtoons Moving, Light Shop and Timing. Again also.Kang Full's Webtoon universe goes like Apartment (2003),Timing(2005), Neighbour (2008), Again(2010), Light Shop (2011), Moving (2015), Bridge(2018), Hidden(TBD).Out of all these comics Apartment and Neighbour are least connected. Young Tak (Time Stopper) first appears in Timing but there are also other time manipultors. We saw Young Tak first in Moving drama and Now again in Light Shop.So we will see him in Moving Season 2 as they will adapt Bridge story which is sequal to Moving. But also I guess Hidden as well. Because Frank and US Superhero agents were supposed to be villains in Hidden. They don't appear in Moving or Bridge webtoon. There is also Detective and Young Tak connection, In webtoon Detective is also a main character in Timing and Again. He knows Young Tak since Young Tak was in highschool but here that's changed.There also other grim reapers in this world.Kang Full must be having a grand plan for all the characters as I think He will also add new original stuff in season 2. He is currently writing script for season 2.

No but he is much more durable and has lot more pain tolerance than normal people. He is killing machine but will need to go to the hospital. Most probably Mother stiched him.

No they are not pretending they are being mentally controlled by MOM. MOM must have a trigger to activate them , other times they genuinely are a family it's just that with some trigger they get controlled. Just like how FL(Mother) can control anyone by saying "Attention". They must have gotten programmed before running the facility.

I love all the family members, they are perfect.
All the actors did great job, If this drama was on Netflix or Disney+ it would have been a huge hit.
I don't know if they have announced a season 2 or not yet but they need to as I wanna see what happens next. It ended up on an interesting plot twist.

They are not playing her, They are being controlled by MOM, MOM must have trigger from them to activate them to give her the reports.
