So he did level up but that fear should be gone by now or well residual fear
There are traumas/fears that are hard to forget even if many years has gone by, so I understand why the MC still feels scared even after 3 years.
Guess so but this is a world with status effects so he shouldve gotten a skill to resist it
He did say he stopped his ageing so he could remember the emotions he felt in the betrayal 3 years ago. Fear must be one of them.
Oh must've missed that
Interesting if you ignore the harem trash. However 3 years and he still flinches at the monsters so did he even attempt to level up
