He does have alot of character development throughout the story. If you expect him to be like some shounen mc and suddenly get op it will never happen. mc knows his limits and tries his best to do beyond what even he can manage at times which has negative ramifications on his psyche and body. The story is realistic for the setting. The story reads more like a psychedelic horror for the most part.

MC is not whiny if you think about the setting of the story. Necromancer is a class that mc practically pioneers because no other of his class has advanced to his level of mastery. He will always have his limits in combat as his class is not designed for him to solo combat things. I will say that later on the story delves deeper into his psychological strength and just how much the familiar contracts take a toll on him and how he learns to deal with his various circumstances.
I paused at chapter 3... so is the mc (necromancer) gonna have a wonferful characters development (aka grow a spine) or will he remain whiny / dependent on dawon?
