The man in the hood/veil is TOTALLY the ex-fiance. Hairstyle checks out. Arrogant-won't-hide-my-ki checks out.
Also, poor kitty Zombifying warriors also is a brutal and grotesque way of NOT honoring the dead. It's despicable.
The guy is definitely the "ml" in "disguise". Lol not even trying to hide his ki in the black market. The good news is Haewon's got her first real lead now. Tbh the idea of that medicine irl would be scary af.
