Read until the latest chapter, MC just doesn't seem like a player that cleared/finished the game at all or gamer in general, somehow when the heal use some skill he will get surprised by it?? And if I met monster in game irl, I will be comparing it, not just surprised like you never seen these monster before.
The first time I saw Isaiah I already know he wont be endgame, it extra hurts when MC chooses Claude（/TДT)/ (I love Claude too but Isaiah more) ughhhhhhhhh why I always liked second ML more
