“Moonlight Drawn By Clouds” episode 6 will see our heroine Hong Ra On (Kim Yoo Jung) in grave danger after her real identity is revealed.

KBS2 has released the teaser for “Moonlight Drawn By Clouds,” also titled “Love In The Moonlight,” episode 6, which showed Crown Prince Yi Yeong (Park Bo Gum) getting closer to the finding out about the connection between his eunuch and the mysterious dancer who caught his attention on the night of his father’s birthday.

However, Eunuch Ma (Choi Dae Chul), the one who knows Ra On isn’t actually a he, appears to have revealed the truth because one scene shows Ra On being arrested by the palace guards. But it looks like Yeong won’t let them take her away because he draws his sword on the guards holding Ra On captive and demands for them to release her immediately. “I’ve never had anything taken away from me before,” Yeong tells Prime Minister Kim(Cheon Ho Jin) , who’s there to witness the proceedings.

Yeong isn’t the only one who wants to protect Ra On, however, as Yoon Sung (Jung Jin Young) is also doing whatever he can to hide her secret, including threatening Eunuch Ma with a gun to leave Ra On alone.

Meanwhile, Yeong’s bodyguard Byung Yeon (Kwak Dong Yeon), who is also hiding some secrets of his own, is told to investigate Ra On and find out if there’s anyone important around her. This could be a hint that the group Byung Yeon is secretly working for might be planning to use Ra On against Yeong because of their closeness.

The “Moonlight Drawn By Clouds” episode 6 preview also showed Yeong meeting Jo Ha Yeon (Chae Soo Bin) in the palace. While practicing archery, he accidentally aims in the wrong direction and ends up shooting his arrow in Ha Yeon’s direction. Luckily, Ha Yeon is unharmed because she managed to duck on time, but still Yeong checks on her with concern. Based on her character description, Ha Yeon is supposed to Yeong’s future betrothed, but it looks the prince either still has no idea about the possible future engagement or doesn’t know what the name of his future wife.

Meanwhile, the historical drama got another ratings boost for Monday night's episode, raking in 19.3% viewership, according to Dramabeans. "Monster" finished second with 9.4% ratings, while Lee Jun Ki's "Moon Lovers: Scarlet Heart Ryeo" dropped to 5.7%.
