Our MC nearly killed himself rushing through the labyrinth in chapter 16 to save Yuel when he thought she was in danger.
Our MC got imprisoned by the other gods for daring to oppose the idea that humans should be slaves of the gods. He was imprisoned for 1, 600 years unjustifiably by those evil gods, and he does not feel any need at all to get back at them. Furthermore, the light god who released him talks to him as if he were her lover. What kind of lover imprisons their lover for 1, 600 years?
When I see the MC's mother taking credit for his work I get angry for the MC. It's disgusting behavior from a mother. The MC's rightful place in history has been stolen, and he does not even care. The MC's lack of caring or even understanding how amazing his work is, is even worse than his mother's behavior.
