A convenience store in Seoul at 3 a.m. in 2013.

When Kang Jae-hoon was feeding stray cats with fish cake skewers, he was spotted by actor Hwang Jung-min.

Since then, there has been an "outlier" in the entertainment industry of the Peninsula -

he was the young man who woke up the extras with a real slap in "International Market", the drama geek who secretly learned Yoo Ah-in's micro-expressions on the set of "Veteran", and the Go Hwan who made the audience cry in "Reply 1988".

From the double-layer refrigerator in the shared house to the red carpet in Chungmuro, Kang Jae-hoon's road to advancement is full of absurdity and passion:

the sharp-tongued roommate Lee Sung-kyung hid expired rice cakes while calling him a "defective product";

the nation's first love Bae Suzy anonymously donated her salary to the family of the trainee who committed suicide, but showed him the AA bill;

the perfect goddess Im Yoona knocked on his door late at night just to confirm whether her mascara was smudged during the kissing scene.

Huang Zhengmin sneered with a cigarette in his mouth: "Kid, remember this - actors are either commodities or lunatics."

When Jiang Zaixun held up the Blue Dragon trophy, the camera swept across his yellowed notebook, and the last page read:

"The camera does not lie, but the audience will never know that I learned rock climbing so that I could carry Yoona out of the fire, I took the motorcycle license so that I could carry Suzy away from the illegitimate fans, and I practiced vacuum belly... just because the Bible said I looked like a pregnant raccoon."

This is a story about a "defective product" that became a specimen of the times.

The story follows a former "playboy" who transmigrates to a peninsula in 2009. Not only does he come from a powerful family, but he also inexplicably acquires a "simp system" that he finds utterly despicable. He randomly assigns the system to a girl, only to discover she's a resolute woman with no interest in romance. What? All the mission rewards go to the goddess, while all the daily punishments are his? Then there's no point in completing missions. He could just use his charm to boost the goddess's favor and exploit system bugs—wouldn't that be better? He'd rather use that time to torment other people's goddesses.

After knocking down his senior Song Yuqi, Zhou Ping discovered that his ears had become different.

He discovered that this future diva was the only "switch" for his musical talent.

When she smiled, the sound of nature filled his mind; when she left, he instantly turned back into a mortal.

In order to prevent his talent from being "powered off", he can only transform into the most mysterious composer PZ

One divine song after another "feeds" her across the border even though she is far away on the peninsula.

Years later, they met at the summit. Song Yuqi looked at the legendary producer in front of her and exclaimed in shock, "PZ...it's you?!"

Zhou Ping smiled helplessly: "Senior sister, if you don't come back, my world will really be silent."
