Wasn’t this supposed to be a strategy game?

Read manhwa Wasn’t this supposed to be a strategy game? / 이거 전략게임 아니었나요
I’ve possessed a hidden character in a notorious strategy game with a 0% clear rate. To escape this game, I must bring peace to the empire… “So, from now on, I’ll trust only you, Priest.” “You’d better give up on that plan.” “Priest, did you really use me?” “For some reason, I feel something special from you, Priest.” “You promised you’d come back.” …Why is my favorability rising, and why does it feel like this is turning into a reverse harem? Excuse me, wasn’t this supposed to be a strategy game?
