Seeing a lot of hating on the blonde ml and wanting the black hair in my opinion it make more sense that it’s the 2nd ml he actually progressed the plot and he legit saved her his past life risked dying several times just to help her while the black hair ml just had cute scenes with her and nothing that would have lasting impact on her ex: blonde revealing he’s a demon even when he know their hated just to help her and also giving her the earrings and coming just like he said to save/help her even tho he was wearing them the other demon show that he cares so much about her not saying the black hair ml doesn’t but in the story it make sense that blonde is the ml since he’s done more for her in the past and the present
