A romantic episode is expected on Monday’s night airing of Moon Lovers: Scarlet Heart Ryeo.

SBS has dropped a teaser for Episode 6 and it hinted an interesting development on the blossoming romance between Prince Wang Wook (Kang Ha Neul) and Hae Soo (Lee Ji-eun).

The sneak peek clip for Episode 6, titled All With You, Hae Soo was also seen in trouble. The video showed the female protagonist will be sold to someone and will be forced to marry him. Prince Wook was seen rescuing her.

Check out Moon Lovers: Scarlet Heart Ryeo Episode 6 preview below.

In the previous episode, Lady Hae (Park Si Eun) asked her husband Prince Wang Wook to marry her cousin Hae Soo. Since she already noticed that her husband had feelings for Soo, she just wanted to see someone taking care of him before she died.  In the past episode, they even almost kissed after Soo risked her life to protect the 8th Prince’s brother, Prince Wang Jung.

However, it seemed like Wang Wook’s mother and sister tried to oppose the prince’s engagement to Hae Soo. Does the 2nd Queen intends to arrange the marriage of Prince Wang So (Lee Jun Ki) to Soo instead? Is Prince Wang So has a chance in winning Hae Soo’s hand in marriage? The two have been getting closer together too. In Episode 5, Prince So surprised Hae Soo by putting his arm around her shoulders.

Moon Lovers: Scarlet Heart Ryeo air on Mondays and Tuesdays at 10 p.m. KST on SBS.
