Ready to be proven wrong very quickly

Idky but I feel like MCs a "zombie" or something The marks arnd his neck and how the ML keeps checking to see if he can feel pain or how much pain he feels makes me think MC is a zombie but idk

Edit: ykw maybe he is a creation like Frankenstein, tbh seeing those marks on his neck made me thought of Frankenstein. So I feel like he was either created (like Frankenstein) or maybe brought back to life (like a zombie) but I'm not so sure, it's just a theory anyways
