"W - Two Worlds" episode 8 will bring some major discoveries for Kang Chul (Lee Jong Suk) and Oh Yeon Joo (Han Hyo Joo).

In the preview released by MBC, Kang Chul and Yeon Joo discover that she might not be as invincible in the comic book world as they initially believed. In an earlier episode, Kang Chul shot Yeon Joo in the chest at point-blank range, but the bullet didn't leave so much as a scratch on her. However, this time, when Yeon Joo accidentally cuts her finger while chopping vegetables in "W" episode 8, her cut doesn't automatically heal. This means that Yeon Joo is now equally as likely to die from a bullet as Kang Chul is in his world.

Things get worse when Yeon Joo finds out that the murderer who's after Kang Chul knows who she is and where to find her. And this might be what drives Kang Chul to push her away and tell her to go back to her world and forget about him.

Meanwhile, "W" episode 8 was canceled this week due to the 2016 Rio Summer Olympics, Soompi reported. MBC released a statement Thursday confirming their decision to prioritize important Olympic matches over the next episode of the drama. “Today’s broadcast schedule is women’s archery with North Korea vs. South Korea as well as a fencing team event. Therefore, ‘W’ is planned for postponement," stated the network.

MBC initially wanted to push back "W" episode 7 to next week as well, but the network later decided to air the installment during its regular timeslot due to heated response from viewers. MBC's decision paid off as "W" received 13.8 percent ratings on Wednesday, a 1.6 percent improvement from the Korean drama's sixth episode, according to the outlet.

"W's" rival, "Uncontrollably Fond," which stars Kim Woo Bin and Miss A's Bae Suzy, also got a small ratings boost despite the Olympics competing for viewers and received 7.9 percent for its 11th episode.
