it'll benefit the mc because people still think he's recovering from his coma. in terms of political power, he has none. so he won't be able to protect himself from people that'll get suspicious of his strength or try to take advantage of him.
so as much as i hate the blonde girl, she'll be useful in covering up the incident and the battle mc had with the vampire by taking credit for it because she has more political power and people would be more likely to believe her etc etc.
I'm sure the author will do a big reveal and make it so everyone will recognize mc for his powers but I'm sure that'll be for a while. who knows.
I think her taking credit might benefit mc since he still hasn’t taken care of the situation with the people who killed him in the past. him hiding his powers a little longer would be good but if he doesn’t that’s fine with me too ╮( ̄▽ ̄)╭
