I feel like the MC has lost most of his original personality? It's not blatantly obvious but I feel like he used to be more shrewd and clever than this, he used to push the plot but now it seems like the plot is just dragging him around like a ragdoll, he is literally going from a country to another just to be played around by the seme who apparently just knows every piece of information and plot point they need to solve this whole situation, btw the seme is such an asshole, he says that he is not making the son pay for his father's sins but he still drugs him, rapes him, uses him for his own gain, traps him in a contractual hell and threatens his friend. like be for real man.
