Since it's only the first season the author has not revealed much about the main plot yet so we should wait for the next season to know more about the story. But can u tell me which part u are confused about.
Like in the manhwa? The only chapter with similar dialogue is in chap103 but if u mean a chapter in the novel, its in Diaphonic Symphonia (Hidden Track, pollack soup)
Xinlu go kys please even ilay is better at after care
