I was thinking here, only 5 survived in the great dungeon 10 years ago, but only 4 left the portal, Chaeyoon said that Kangjin the other survivor was missing, we also know that after defeating the boss a black portal appeared, so what if Kangjin stayed back in the portal using the skill that stops time/decreases the passage of time in the black portal to prevent a breaking dungeon from occurring all this time and that's why he hasn't left the portal and is missing.

I won’t give any specific spoiler but,
*Spoiler *
The other ‘survivor’ is actually just sleeping, they told the MC beforehand to wake them up if they are falling into deep sleep (because of his skill), but the MC just got so shocked and just forget about it and the rest is I guess you better read the webnovel. In the end this ‘survivor’ helped the ML to help MC in the great dungeon final battle.

yeah, they kinda sleep, I mean they sleep like dead person thats why everyone thought this person was dead for sure. And the MC is not on the spot when this ‘survivor’ dead, so the MC just got so shocked ( I think the MC wanted to revived the body of this ‘survivor’ but other revengers said that it wasn’t possible and they need to get into the next stage asap) . And the only one that will meet this ‘survivor’ is just the ML. But who knows in the future, because the ending is like open ending where their journey to the galaxy just begins so there will be possibilities they will meet again, but sadly the ending of the web novel is the beginning of their journey.

This have a novel? If it have one, where I can find it? Bc when I first read I couldn't shake the felling I was missing a lot of information and the story was incomplete and kind confusing, so I dropped bc I was thinking maybe my English wasn't good enough and that's why I was missing, but now I pick this again and nothing change, the confusion and the felling of the missing part still the same. I really like this history, but I can't truly enjoy it bc of this. So if it have a Novel I would like to read.
I was thinking about this and it's good that they didn't found out about the pregnancy yet, bc now they will talk about they relationship without having the weight of having a baby. So they can speak they heart without the influence of the pregnancy and then after they talk found the pregnancy will be a lot better then founding the before the talk. So this way they will have a better foundation for their relationship, will not sound like a relationship bc of the baby, but bc they really want a relationship. ٩(๑❛ᴗ❛๑)۶
That's an excellent point thank you for pointing that out !!
