In the latest episode of drama "Moonlight Drawn by Clouds," Prince Lee Young finally find out the true identity of eunuch Hong Ra-On, a woman who disguised herself as a male.

But the Korean authority put the drama under review after some problematic scene involving a lead female character.

However, the revelation was not new to some characters as they already knew about her true identity as a female, including the crown prince's best friend, Kim Yoon-Sung.

After the prince discovered it, a love triangle is expected to occur because Yoon-Sung has been also in love with Ra-On.

Actor Park Bo-Gum and young actress Kim Yoo-Jung became the male lead character as crown prince Lee Young and eunuch Ra-On, respectively. While Jinyoung is cast as Yoon-Sung.

Meanwhile, some disturbing scene on Kim in the drama prompted Korean authority to review the drama. Korea Communications Standards Commission (KCSC), as allkpop reported, has put "Moonlight Drawn by Clouds" under review.

KCSC considered the scene, where Ra-On bandaged her chest to hide her identity as female is "too revealing." Especially under consideration that Kim is still a minor and the scene took longer than necessary, according to KCSC.

Prior to the official investigation by KCSC, the drama rating has slightly plunged. As reported by The BitBag, there is a 0.5 percent drop of the rating in the last week's episode to 18.8 percent.

Nevertheless, "Moonlight Drawn by Clouds" is still topped the most watched show during the Monday-Tuesday primetime slot. Its competitor MBC's "Scarlet Heart" is currently in the second place with 10.3 percent rating.
