So far in chapter 25, Diana (original MC) has been introduced to Blake (original 2nd ML). Diana loves Ancia and apparently, they're going to have a great relationship as sisters, and I assume that something might threaten Ancia in the future, since Diana wants to be a knight (!) and is training with Blake. Contrary to what was written in the original novel and what Ancia thought, Blake and Diana don't fall in love, but rather, argue about who loves Ancia the most. From what I read, the two are training partners and are good friends (when there is no Ancia in the middle). The first time Blake met Diana, it seems that he didn't feel the power of her light. What makes Ancia confused and wonder if it's only Diana who can save him. The interesting thing is that chapters ago, when the Emperor arrives from the sealing of the Dark Door. He questions Eunhan if Blake suffered a lot or felt pain, because every time the Emperor uses the power of light granted by the goddess of light, the heir of the curse suffers terrible pain. But Eunhan says no, and even shows a "video" on a magic stone of Blake and Ancia laughing after a shower. Which may indicate that Ancia, as heir to the power of light, has unconsciously protected (relieved) Blake's suffering; because it is said at the beginning that Ancia had almost or little power of light, as a descendant. the spoilers r based on the novel
The OG ancia did suicide because she was afraid of blake face, but actually the main reason is because of she think her family already abandoned her and her sh** dad who's always abuse and scold her because ancia is the child of the woman he didn't love, just marry her for money, and there was the OG ancia memory where the count (ancia dad) told her to die by hanging herself or drown herself in the lake.
that was interesting
