@Introvert Then
Spoiler!
Arcian said that then he would sleep in the same room as Camila, but Petro told him not to say stupid things and to follow him to his room because his bed was wide, in the end they both slept in Petro's bed. When Camila told Arcian that she had a dream where the mansion burned and the guardian sword disappeared, Arcian got angry and told her to pack her bags and leave. They argued a little, Camila even called him by his full name "Arciano", but in the end she managed to convince him that she had to stay by saying that he was here with her and that with him she would never be in any danger. Arcian had no choice but to let her stay and simply reinforced the protective magic of the items Ravi gave to Camila.
In the end they were able to prevent the fire and protect the sword, but it was discovered that Camila was the new master of the sword. Duque Javenil was devastated because the master of the guardian sword was not someone from his family. Duke Sorfel teases him saying that his divine beast Jetty prefers Camila and now his sword, and that the sword should be handed over to the Sorfel family.
Duke Javenil was very upset but when he saw Petro watching Camila, a huge smile appeared on his face. He told Duke Sorfel that he would give him the sword if they used its power on behalf of the Javenil Family. Duke Sorfel asked how that was possible and Duke Javenil told him that it was possible if Camila became a member of his family by marrying Petro. Duke Sorfel wanted to kill Duke Javenil for proposing something like that, Duke Sefra (who already wants Camilla as his daughter-in-law) even gave Duke Sorfel a sword to kill him.
I like to post spoilers for the stories I find interesting because I don't have much time to read novel due to busy schedule
