Only the mom would be skeptical but not entirely against the relationship since Jaehyuk’s dad was practically bouncing when they visited Jaehyuk at his house. His mom just thinks that Jaehyuk didn't actually change his playboy ways and is just messing with boys. She'd likely change her opinion (I'm hoping) when she meets Garam.

Does that mean that his father tried to kill him in the prologue? That's what his memory dictates except he framed that man as a burglar first than his father. That's what his first POV tells us. It might be because his memory is a bit twisted but if that's the case, then Guwon is the one who really killed his father.

Based on reviews, MC seems to have trauma and his views about the characters are a bit twisted than what it really was. He's an unreliable narrator so we can't really take his word abt the ML being abusive and stuff. ML is also a good egg, not necessarily the greenest flag in the shed but he turned out to be a golden retriever ML. It's just that MC keeps on painting him on a bad light and the story is narrated on MCs POV that's why the ML looks like a menace.

Deduction.
On the doctor's flashback, Guwon's method is asking everyone first on what they can do for him if he were to spare them then kills them after if they're useless. But in CH1, Jinwoo can't even say what he can contribute to the community and Guwon had to LOOK FOR THE REASON to save him himself which is out of character all things considered.
There could be two reasons.
One. Jinwoo's father asked Guwon to spare his son before Guwon killed him. Maybe he promised him that Jinwoo could be useful to him or something but Jinwoo retaliated against Guwon thus his bloody state and his messy bandage when he woke up. He must have hit his head pretty badly to get amnesia or it could be a trauma response. But this is filled with holes as well because Guwon is quick to violence. I don't think he'll let Jinwoo live if he attacked him before.
Two. Jinwoo killed his father before Guwon arrived. This is even less plausible since there are no indications of Jinwoo's mental instability aside from strangling Guwon in his sleep.
The secret third thing is that Jinwoo's father got killed by the looter in Prologue Chapter who Guwon killed to save Jinwoo. There was also someone who was calling 911 or the police in the BG about their house being looted on.
And lastly, it could be that Guwon is not the only one of his kind because in the Prologue, it was said that THERE WERE THOSE who are waiting for this day (apocalypse) to arrive. This opens the possibility that there could be someone who's similar to Guwon who murdered Jinwoo's father and because he was exposed to a possibly similar violence, he is getting flashbacks of the past.
But ultimately, Guwon remains suspicious because in the Prologue, it is said that his name means SALVATION but it is only LATER that Jinwoo REALIZES THAT IT ISN'T REALLY THE CASE.
