I've discovered a way I can enjoy this game more.
You see, I was naively under the impression that Hectate was the primary antagonist of this story.
This is wrong.
LIN is the primary antagonist. Think about it. Look at the definition of the word " a person who actively opposes or is hostile to someone or something; an adversary: "
Fits Lin to a tee. Especially in comparison to Hectate, who, while certainly manipulative and deceptive, has engaged in actions that directly aid the protagonist, at least occasionally. Certainly more than Lin has done.
Of course I suppose it's entirely possible Lin is meant to be a tsundere, slow burn romance arc, to grow as a character herself and as a partner for the MC through the adversity and obstacles they overcome together, resulting in a satisfying and enjoyable conclusion that felt worth all the work it took to get there.
But if that WERE the case, I think it's safe to say the ball has been thoroughly dropped on that character arc.
