According to Nielsen Korea, episode 6 of the Korean drama "Head Over Heels" (Vietnamese title: Nguu Lang Chuc Nu) has achieved an average nationwide rating of 4%, an increase of 0.3% compared to the previous episode's rating.
According to Wikitree, the drama's ratings are improving due to unexpected changes in the plot.
Based on a famous webtoon, Head Over Heels is a fantasy romance drama, telling the story of a young man haunted by bad luck, destined to die Bae Gyeon Woo (Choo Young Woo), and the young female phap su Park Seong Ah ( cho Yi Hyun) trying to save him from her fate.
Seong Ah fell in love with Gyeon Woo at first sight and was determined to help him when he was harassed by the Devil. After many meetings, Gyeon Woo has increasingly opened his heart to Seong Ah. But in episode 6, the plot had an unexpected change that the audience did not expect.
Gyeon Woo was possessed by the evil spirit Bong Su. At the end of episode 6, Seong Ah went to the abandoned house where the evil Bong Su was residing and faced Gyeon Woo who was possessed by the evil. At this time, in front of Seong Ah, he was no longer a gentle, familiar guy, but Gyeon Woo with cold, strange eyes and voices.
The evil spirit Bong Su in Gyeon Woo's body approached Seong Ah and said: "Hello, phap su. You have to say hello too". After that, Bong Su stroked Seong Ah's face, the episode ended with the scene where the evil Bong Su was in a position to prepare to marry a female phap su.

The change in plot means that actor Choo Young Woo will have to take on 2 roles in the film. According to the content of the following episodes, Gyeon Woo will have to fight against the Devil who comes into his body. Gyeon Woo's personality and expressions will change constantly when interacting with Seong Ah.
Actor Choo Young Woo surprised the audience with his cold eyes and sinister expression after being possessed by a demon, completely opposite to the image of a male student who was always shy and afraid of contacting others before.
To increase the excitement, the producer released a new poster for the character Gyeon Woo when possessed by a demon. Choo Young Woo's change in expression received many compliments.
The production team said: "The story is at an interesting turning point, Gyeon Woo must fight to avoid being swallowed by an evil spirit, and Seong Ah risks her life to protect him. The audience can look forward to Choo Young Woo's acting, he perfectly portrayed these two contrasting characters."
The interesting thing about the film's content was also revealed. The reason why the evil Bong Su entered Gyeon Woo was because he liked fairy tale Seong Ah, he wanted to take over Gyeon Woo's body to be able to meet and interact with Seong Ah more.
This new plot is also seen as a strong catalyst for the love relationship of the couple Gyeon Woo - Seong Ah in the second half of the film.
Bong Su's demons have not appeared for much, but this is an opportunity for actor Choo Young Woo to once again prove his ability to act flexibly in many different types of roles.
Previously, Choo Young Woo was considered a promising face with impressive performances in the series of films " trauma Care Center", "The Legend of Lady Ok", "Khong Ton".
