The 10th episode of ENA’s Thursday drama Battle for Happiness (written by Joo Young Ha, and directed by Kim Yoon Cheol), which aired on the 29th, introduced another mystery related to Oh Yu Jin’s (played by Park Hyo Joo) death, intensifying viewers’ interest. As a result, the viewership rose to 2.734% (based on Nielsen ratings in the capital area), breaking its own record for the highest viewership once again. The peak viewership reached 3.47% per minute.
On this day, Jang Mi Ho (played by Lee El) deduced that Kang Do Jun (played by Lee Kyu Han) had perverted tastes based on a post presumed to be written by Oh Yu Jin on an anonymous online forum and information collected from a secret gathering of the fathers at the Herenity English Kindergarten. Furthermore, Mi Ho finally discovered Do Jun’s video in Oh Yu Jin’s “Pandora’s Box,” and this fact left Ji Yul frustrated, knowing that she had seen the video as well.
However, despite Mi Ho’s confirmation of the video inside the USB belonging to Oh Yu Jin, Kang Do Jun confidently stated that it was something he had agreed with Yoo Jin to cover up. Moreover, he blamed Mi Ho for Yu Jin’s death and shocked her by revealing that Yu Jin’s last words to Mi Ho over the phone before dying were, “Die. You’re terrible, just like you are. I wish you were gone. Please die.”
To determine whether Kang Do Jun’s words were true, Mi Ho opened the “Mi Ho” folder in “Pandora’s Box.” Inside, she found a document filled with malicious accusations against herself. Deeply hurt by Yu Jin’s writing, expressing how regretful she was for the time they spent together, Mi Ho broke down in tears, feeling despair.
