-Kiyoung sees Raphael losing the fight against hyunsung. So he helped Raphael. Hyunsung who were losing accepted Lucifer's power and turned into a doom hyunsung. He looks twisted and all. Only sees kiyoung and almost killed of Raphael brutally. He even tried persuading kiyoung to leave the continent with him so they won't suffer by the hand of the upper beings like benignore. Kiyoung were truly afraid of this hyunsung who lacks sanity

Also there's 4 archangels who remembers the first timeline. Among the 4, 1 hated kiyoung terribly. 1 likes kiyoung so much he even thought kiyoung were forced to be the masked man. The 4 of them died by kiyoungs people and later will be revived along with kiyoung. They revived with their memories wiped and body in child form. Kiyoung then take them in as his adopted children's

from what I remembered correctly, the main story didn't really include 1st timeline or did hyunsung exactly know kiyoung is the masked man (like he try to not think about that), but in the extra it was explained in the 1st timeline hyunsung is one of the peoples who makes kiyoung on the destruction path (deokgu died, the city they (kiyoung deokgu) lived is destroyed and hyunsung is one of the people who agree that city to be destroyed)
I've dropped this multiple times and finally decided to sit down and read the whole thing and now I've caught up(in a week, which is a new record for me) . I need spoilers. I really need spoilers. Pls anyone
