In episode 5, Crown Prince Sajo Hyeon lets Ak-Hee take over his mind and body to save Hong Ye-Ji’s Kyera. They jump into a river to save themselves and end up kissing each other in the water. The next episode begins with Sajo Hyeon returning to his senses and pushing himself away from the kiss. Later, the two part ways, but Kyera comes back to protect the crown prince from getting stabbed.
In Love Song for Illusion episode 6, Park Ji-Hoon’s Ak-Hee is furious when Sajo Hyeon returns to his senses. After coming out of the water, Kyera explains everything to the crown prince. When she begins to leave, he stops her, claiming that he still thinks she is not innocent, referring to the king’s murder.
On the other hand, Sajo Hyeon feels at ease when she holds him tight, and he gets chills as Ak-Hee tries to summon him. They change into commoners’ clothes and shelter in a villager’s house. The two share some heart-fluttering moments as they stay together in a room. The next day, Sajo Hyeon decides to let Kyera go. While bidding farewell, he asks her if she will rejoin the Wind Knives (a rebellion group). She mentions she will not let Hwang Hee’s Sajo Yung become the new king.
For context, Sajo Yung is an illegitimate child of the late king and half-brother of the crown prince. He is part of Wind Knives and has manipulated the villagers against Sajo Hyeon. Due to the manipulation, a group of villagers form a rebel group to kill Sajo Hyeon and let Sajo Yung take over the throne. Hong Ye-Ji‘s Kyera finds out about it after the crown prince leaves.
While Sajo Hyeon heads back to the palace, a big commotion happens. The royal guards beat up innocent people, and a few commoners look for the crown prince. When a man gets hold of Sajo Hyeon, he tries to stab him, but Kyera appears at the right time. She and a few Wind Knives men save him.
After Kyera brings Sajo Hyeon to a safe place in Love Song for Illusion Episode 6, she asks him to fight back. But he says that he will not go to the palace and will do nothing as he deserves to die. Kyera gets furious and mentions that Ak-Hee is better than him, so he should let him control his mind.
Kyera’s words hurt him, and he holds her tightly against a wall, stating that he fears that he will end up like his father. The next scene shows the crown princess and her father revealing to Sajo Hyung that the king’s murder weapon belongs to his mother. To save himself, Sajo Hyung orders the guards to lock up his mother. His plan to take over the throne fails when Sajo Hyeon returns.
The crown prince takes over his birthright and becomes the new king. He notices his wife has demoted Kyera from Concubine Hyo to a maid. She mentions to Sajo Hyeon that his lover happily accepted her fate. He then recalls telling Kyera that he wanted her by his side so he wouldn’t end up like his father.
