I think that's cause not much is known in general regarding Seo Chaeyoon
The only people that know his powers and face are the surviving Avengers that battled the great dungeon the first time and they kept their mouth firmly shut (two sadly also took their life)
While some skills seem to be known (like the great shield or sth), it could always be just one skills of many; like for example he could be or act like the fire dude and hide his great-shield und gaia skills
He does have other skills like the blitz/spark thing after all and no one knows about his personality
It should also be taken into consideration that they still shouldn't be sure that Seo chaeyoon is definitely under the candidates they summoned. After all they searched for 2 years -there had to be many disappointments
But I agree, it definitely seems a little bit too obvious
I kinda wished he could have hidden it better :/
Oh I was under the impression that shields were thing seo chaeyoon was most known for so I was kinda confused about how obvious it would be
Because they don't know who Seo Chaeyoon truly is, and his face remains to be anonymous. They might believe that Seo Chaeyoon's been using other skills/items to keep his identity hidden. MC's shield skill is obvious, but he's hidden it's strength by writing a false profile for it. If this deception makes sense.
Idk if I missed something or I'm stupid but why isn't it obvious that Yoon Seo is Seo chaeyoon when he's the only one among the candidates that can make shields??
