Well very soon or maybe in the next chapter
Spoiler!
A loud crash came from the room where the First Prince was currently being detained in. “Medicine! Bring me the medicine!” Desperate screams also leaked through the crevices of the door. At around early evening when Astana had woken up, ever since then, he had started screaming like that to no end. “W-What should we do...” A prince was still a prince, even if he was imprisoned for an unforgivable sin. Two maids who were assigned to clean up the mess of such a prince became anxious and were at a loss at what to do once they heard the sounds that had leaked out from the inside. “I’ve already given you all the medicine though” It was when the maids whose eyes were shaking nervously because they couldn’t stand it, that someone said, “There’s no need.” A low voice was heard from behind them. “Your Highness, the Second Prince!” The maids’ faces brightened immediately once they saw Perez with the imperial knights.
“You can come back tomorrow morning. Go back.” At Perez’s command, the maids ran out as if they were fleeing and didn’t want to be caught again. “Let’s head in.” Lord Sloan was leading them. As soon as the door opened, Astana’s shouts broke loose. “Hey! You! Do you think you can tie me up like this and leave with your neck intact?! Let me go! Now!” Astana, who had one foot tied to the bed, contorted his whole body and screamed. “I’ll kill you for insulting me like this!” Astana’s shouting stopped shortly after Perez entered the room. “Astana Nerempe Durelli. We’ll start the interrogation of your failed assassination attempt on the Emperor and treason.”
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
