To be honest, Alan was rather surprised with how fast Yura's attitude changed right upon finding out that Sharon came from the Sin Family, a same ranking family as the Han Family.
However, Alan just treated it as if this was how Yura normally acted toward others, and during the start, the way he had acted was indeed a little rude. Therefore, it was only normal for Yura to act so friendly toward both him and Sharon once she had found out that Sharon came from the same ranking family as she did.
As for the reason why Yura was acting so friendly toward him too, Alan reckoned that Yura must have thought that he came from a middle-ranking family too.
Not only was Alan surprised, even Yeon himself was rather surprised too, and to be honest, Yeon felt much more surprised compared to Alan.
