He really has it worse than any other characters I ever saw, not only does he return by death, remembering the pain he had to go trough and as a result becoming numb to it, he also goes trough other's trauma, and since he's such an empathetic and good natured person he just cannot ignore others suffering, he takes it to heart. I think having such an ability would be easier for people like the red flame guy in the first chapeters, that doesn't give a shit about others. Props to him and his strenght, he has all my respect.
It feels so good when everything you guessed was right, that's the fun part of reding mistery works.
I have another theory
I always asked myself how the female lead of the novel persona (forgot her name) could exist if the last descendant of the light family (aisha) was supposed to be dead. She was probably the result of aisha's dead body being ressurected.
Maybe the church itself isn't evil, maybe they're all victims of the brainwash by blond dude
He really be negotiating medical fee's costs at your deathbed bruh lmao
