According to a blog and some reviews, in the last volume, it's the day of the ball came where Merdi falls in love with our ML, and unlike in the past, the first opponent for the prince was FL. Merdi's anger and defeat hurt Jenna, and Aydin defeats Merdi with force and drives her out. Merdi, the princess of Ferdi, who was struggling as an Anhamu? in Zeldion returns. Ferdi's Emperor orders Aydin to kill the Second Prince of Zeldion. Unlike in the past, the owl subpoena flies and FL returns to her home country, Ferdi, for revenge, but the Emperor, aware of Aydin's betrayal, traps Aydin in a dungeon. At the same time as she escapes, ML comes to rescue FL and makes perfect revenge, by watching Ferdi's destruction without killing it. After the war, ML handed over his right as emperor to his brother and left with Aydin. (Honestly, after all that they have probably gone through, the choice of having less drama and more time to travel and relax together, seems like the right way to go).
