Go Youn-jung,

[TV Report = Reporter Lee Hye-mi] In 'Moja Mussa,' Go Youn-jung gave in to Bae Jong-ok's provocation and revealed her identity. Koo Kyo-hwan ended up working with veteran actor Sung Dong-il in his debut project.

On the 17th episode of JTBC's 'Everyone Is Fighting Their Own Worthlessness,' Euna (played by Go Youn-jung) revealed to Dong-hyeon (played by Choi Won-young) that she is Youngsil, while Dong-man (played by Koo Kyo-hwan) was shown signing a contract with Kang-sik (played by Sung Dong-il).

That day, Jeong-hee (played by Bae Jong-ok) visited the Choi Film office with an armful of snacks, and unlike Euna, who looked troubled, the staff all said, "Her presence is no joke" and "She really is generous," in unison.

Facing Jae-young, Euna's ex-boyfriend, Jeong-hee said, "The idea that all humans are bundles of emotions, absolutely relatable. How did you come up with something like that? Whether you have great parents or terrible parents, without all that nonsense, every human is born in a bamboo shoot, so there is no one to blame, and this is heaven. Why couldn't God think of something this simple? I even read the lines out loud because I wanted to try them all on my lips. The writing was very deep. Director Ma seems more interested in women than men," sharing her thoughts on 'Knock Knock Knock.'

Jae-young only gave an awkward laugh, and Jeong-hee continued, "Why did you make the protagonist a man? It’s a script that wouldn’t have any problem if the lead were changed to a woman. 'Knock Knock Knock' is not the kind of writing that works just by acting. What matters is an actor who has that sensibility built in. To really bring out its flavor, you need an actor who understands the depth of the writing and can act down to the decimal point. If an actor comes in who acts too hard and turns everything into his own movie, it’ll be a disaster," she advised.

She went on to appeal, "I could see the bones had been ground into it, but could you endure the site collapsing while filming with an actor like that? I understood it down to the bone."

Jeong-hee already knew that Euna was the writer of 'Knock Knock Knock,' 'Youngsil.' When Jeong-hee asked why she chose the pen name Youngsil, Euna snapped back, "Whether it’s a husband or children, you’re supposed to make everything attached to you special so it stands out. But I still remember that look in your eyes, as if you were seeing something wrong when you looked at a slow, quiet child. In the end, you gave up on both your husband and your child."

Jeong-hee countered, "If it can become a theme, it’s desire; if it can’t, it’s greed. It’s enough to be a theme, so why should I live suppressing my desire? I think you’re even more fake. If you wanted people to know I’m Youngsil, if you wanted them to know my share in 'Knock Knock Knock' is huge. And yet you hide behind a pen name because you’re afraid people will tear you apart, while deep down you’re feeding your own self-adoration. You must be in hell right about now. You can’t stand Ma Jae-young taking it all alone."

She added, "Just go public. Say, ‘I am Youngsil, I am the daughter of Oh Jeong-hee.’ You act so brazen with CEO Choi, right? Could you have done that if it weren’t for me? Fine, keep bullying me. Weren’t you secretly thinking you’d make me ridiculously embarrassed later? You said I’d do insanely well. You said if I ever acted like I knew you then, you wouldn’t let it slide. When were you ever shining? Hiding behind a pen name." She struck at Euna where it hurt. Euna suppressed her anger with a forced laugh, then screamed and suffered in pain.

Meanwhile, when Dong-hyeon angrily said, "There are people who lecture others on their writing and end up thinking it’s their own. Want to write under Youngsil for just one month? Want to painfully realize your level?" Euna revealed the truth, saying, "It’s me. I’m Youngsil. The writer Ma Jae-young desperately wants to hide."

Near the end of the episode, Kang-sik was shown drawing up a contract for Dong-man's debut work as the lead, foreshadowing an even more exciting turn of events.
