I read ahead in the novel cuz I couldn't wait and I just want to say I LOVE YOU EMILYY

Spoiler Alert
I'll start at the where chapter ends to get started on my rambling.
Penelope finds Yvonne rummaging in her room for the missing fragment piece. Penelope and Yvonne confront each other (this part was kind of scary). Noticing something is wrong Yvonne attempts to forcibly brainwash Penelope. She almost got brainwashed but due to the system Penelope was able to break free by chanting a spell. This spell caused critical damage and made her fall unconscious. Right after two people came inside the room, the head maid and Emily. The head maid ran to Yvonne's side, who's unconscious, then threatened Penelope. Blocking her from leaving the room until she suddenly collapsed to the ground. Behind the head maid was Emily holding a stool. She knocked the head maid unconscious and tied her up with Yvonne. She gave Penelope a male servant uniform and ushed her to quickly leave and run away.
Here's a small part from the novel:
Honestly, I was not a good owner for her if I thought about it. Emily was loyal to me, but I always doubted her. So..... I really didn't know why she help me like this. My heart was throbbing. I should have done better, I was overwhelmed with regrets.
"... I'm sorry."
"No need to be sorry! I'm your dedicated maid."
Emily replied with a smile as always. And as if trying to reassure me, she whispered with a humorous expression.
"You make us look like villains, don't you think? We just caught a real villain."

Okay I read ahead more to update you. It's a bit long with details of each interaction to explain the scene better. ^-^
(Vinter interaction)
Penelope runs away in disguise, taking a carriage to see Vinter. She asks for money along with the mirror fragment back but Vinter insists on keeping it for safety reasons. They began to discuss about our the mirror of truth, a relic, after Penelope brought it up.
Leading to the conclusion that Yvonne is Leila, and entity or demon. Penelope confirmed this by telling Vinter what happened back at the mansion where she got brainwashed and didn't see Yvonne's reflection. Vinter began to feel guilty by dragging Penelope into this mess. Seeing Vinter filled with guilt, Penelope felt useless. She insisted on taking the fragment back and running away since she didn't trust Vinter with it as he can get brainwashed at any moment (in normal mode he got brainwashed when going against Leila and fell in love with Yvonne). Vinter then leads Penelope into a space connected to his unconscious mind. He explains that if he gets brainwashed or dies then everything inside the space will be destroyed. Inside the space was the mirror fragment hidden underneath the roots of a plant but he doesn't give it to Penelope and instead asks for Penelope to take a purple flower. He explains the meaning of it, roses represent love, purple rose are ambiguous, an imperfect love and complete love. The purple petals began to fall one after the other as Vinter shares his feelings, realizing he ruined everything. He lifts up his mask, showing his tears. In exchange for his trust he lost his affection. Vinter plots against a way to neutralize Yvonne and help Penelope's maid. They bid farewell.
(Derrick interaction)
Upon leaving Vinter's office she bumps into Derrick and the Eckart soldier's who were looking for her. She runs away but Derrick recognizes her due to the magic bracelet he gave her. He begs for Penelope to come back with him. They get into an argument and he questions why Penelope is distancing herself from him. She simply said it is because she hates him. He falls further into the abyss with guilt and regret. She then teleports away with a magic scroll Vinter gave her.
(Callisto interaction)
Penelope teleports to Tratan where she buys a ship and crew in order to reach Arkina islands. When they departed out to sea in the middle of the night for less active monsters and calmer waves. But in the middle they get attack by a monster. A huge Kraken appears and a event starts. Penelope has to use magic to cut the legs of the Kraken in order to defeat it. She attacks the Kraken by cutting it's leg with magic but it wasn't counted into the system. She tries again and it doesn't work until the legs of the Kraken regenerate twice as much. Meaning the legs increases when she attacks. Just when she is about to launch another spell she spots an attack coming at her but not enough time to react. A voice calls out to her as he cuts the leg with his sword. The crown prince appears and they worked together to take down the Kraken. Cutting it's legs and using fire on the surface. After the battle Callisto express his deep concern, worry, and relief for Penelope then proceeds to hold her tightly in his arms. They get interrupted by the crew as they arrived near Arkina islands. Penelope questions how Callisto knew where she was going until she looked at the map he was holding. She realized he tracked down her location through the map that was identical to hers. He had a replica of the map that identified Penelope as the owner. Then they had a cute little moment where she calls him a stalker and delusional, he calls them lovers and pulls her into a kiss. ^-^

I found this website to read on. But I read the novel from this PDF I downloaded from Z-Library. The translation aren't great with minor Grammer mistakes but it's easy to understand. Hope this helps ^-^
