The cracked part is a piece of seohos shattered soul that junmi (? I forgot his name but bihwans brother/cousin aka sinner from the underworld) forced into minchans soul to make him the perfect vessel to bring back seoho after he was banished
Oh now I remember, thanks (▰˘◡˘▰)
Why is minchan’s soul a little cracked did I miss something ? (I guess that’s why the poor thing was crying)
