I think this comic's timeline is way before in the sweet home
This is a prequel meaning all of this happened before Sweet Home. There's no Hyun in this story.. only Hyuk has been introduced as Gyuhwan's friend (crewcrew). This is back when Hyuk didn't even know Hyun. Also in the last chapter of Sweet home we got to know what happened to Hyun.. maybe you didn't read it? Or I just understood you wrong ┑(￣Д ￣)┍
Oh sorry I'm so bad at names it seems like I wanted to say hyuk god damn it korean names are so hard.
And nope ending of the sweet of we saw both hyuk and hyun turning egg but only hyun come back so we are not sure what happens to hyuk. He wake up, that's our speculation bcz author didn't show it clearly.So I'm going back to my sad self damn it.
But yeah you're right it's a world before the sweet home I thought it was after bcz of the naked legs in the last chapter but in first chap hyuk said maria from the sky finale episode so it's totally before the super human guys. I was so happy to see hyuk now I should cry.
Sweet home spoilers
"maria from the sky" "crewcrew" "all that beep shit" "naked super humans" hell yeah baby sweet home universe. But I mean how did world get better in such a short time hyun doesn't look too much older yeah how about whole destroyed world did super humans help or something it doesn't make sense?
And fuck I did really get fucking angry when we couldn't even know if hyun was alive or dead (he is my favorite character for fucks sake sensei) in finale of the sweet home but shit my my heart is back to life again
