Itaewon Class may be one of the most inspirational series I’ve ever seen. There is tremendous power in seeing one person doing all he can to achieve a goal. It’s another thing when that person inspires others to do the same by placing his faith, trust, and love in them. And Gwang Jin’s poem, “I’m the Diamond” which is read at the end of the pivotal 12th episode, sums up everything that the series is about.

Park Sae Royi is a young man who loves his father dearly. Sae Royi is a principled man who believes that people should be treated appropriately. Upon seeing a fellow high school student being bullied by Jang Geun Won, he intervenes. Sae Royi doesn’t realize that Geun Won’s father, Jang Dae Hee runs one of the largest corporations in the country. Of course, this is another series where the corporate bully steps all over the weak. Dae Hee demands that Sae Royi get on his knees to beg for forgiveness, even in the presence of Sae Royi’s own father who works for Dae Hee. Sae Royi refuses and is promptly expelled. Fearing his father’s disapproval, Sae Royi is shocked to learn that his father couldn’t be prouder of a son who sticks to his principles unwaveringly. When Sae Royi’s father is killed in a hit-and-run accident by Geun Won, this sets in motion a chain of events that provides Sae Royi with only one goal: the destruction of Jangga Co., the downfall of Dae Hee, and Geun Won brought to justice for his crime.

Kobe Bryant’s English teacher once told him, “Rest at the end, not in the middle.” Sae Royi is a patient man with his eyes never wavering from his goal. He spends seven years after getting out of prison doing odd jobs, reading Dae Hee’s biography, and arming himself with money and knowledge to carry out his plan.

Sae Royi is one of the most inspirational characters, who reminds me a lot of Rocky Balboa; the little unknown “David” attempting to take down “Goliath.” He opens a small pub in Itaewon. It doesn’t take us long to see how much faith and trust he has for his employees and friends. He believes in them even when they don’t believe in themselves. He harbors no ill-will toward them, but he’s also quick to call out any of them if they mistreat or disrespect others. I’m sure that many would love to work for a boss like him!

Sae Royi’s true weapon, however, comes in the unlikely form of Jo Yi Seo, a young woman with an IQ of 162 who runs her own blog, carrying a massive platform of followers and subscribers. She’s rough around the edges, to say the least. She speaks her mind, never apologizing if her views and remarks hurt someone. To her, being honest with the truth is more important than tapdancing around with trivial and whimsical flattery that does nothing. While Yi Seo can be a little irritating at times, this girl knows what she wants and will do whatever it takes to attain it. She is so vivacious and direct that she doesn’t even think twice about telling Sae Royi that she likes him, or even warning those who get in Sae Royi’s way, that she will crush them. Kim Da Mi steals the series, in her depiction of Yi-Seo, in my opinion. She captivates and intrigues in every, single moment she’s on the screen. I’ve only seen her in “The Witch,” and “Our Beloved Summer,” but I’m enthralled by how diverse her characters are and how well she performs them. Yi-Seo quickly became my favorite character of this series. Tell me someone who wouldn’t want a veritable tigress for a companion; someone who will be in those trenches with you through thick and thin?

On the other side, we have Oh Soo Ah, who is Sae Royi’s high school classmate and protégé of his father’s. Oh Soo Ah is someone who will always straddle the fence; someone who is afraid to stand up for anyone or anything. At heart, she’s a true coward which is what all fence straddlers are. Too afraid to pick a side/position, they sit and watch. Oh Soo Ah loves the fact that Sae Royi likes her, but she makes no apologies for being completely unprincipled, including accepting money and working for Jangga Co, regardless of what happened to Sae Royi’s father. She is also incredibly superficial and selfish. Fortunately, for Oh Soo Ah, Sae Royi doesn’t hold it against her. He’s a bit naïve and gullible when it comes to Oh Soo Ah. When we see Yi-Seo with Oh Soo Ah, it’s easily apparent who the stronger woman is, and it’s hilarious each time Yi-Seo hits Oh Soo Ah with the truth of why she’s such a coward, exposing her at each and every turn. Yi-Seo is nobody’s fool, especially Oh Soo Ah’s.

Also take notice that Oh Soo Ah has a list of conditions that Park Sae Royi must meet in order to date her. Yi-Seo has none. And love never has conditions.

It's a true pleasure watching the journey of Sae Royi and his employees as they slowly rise up, deal with setbacks and even being virtually knocked out, only to come back stronger than before. They may get knocked down, but they keep getting back up. Slowly, we can see the believing in people and treating them right, begins to gain footing against Dae Hee and his unprincipled manner of doing business, where people are nothing more than pawns to be used, including his own sons.

The story arc even takes on discrimination, and beautifully so, as Sae Royi hires the black son of a Korean father as well as a transgender cook. In a world where transgenders are mocked, reviled, and frowned upon, the series strikes its own high point when Hyun Yi is about to go on a cooking show, and she’s betrayed when her “transgender” status is made public. While Sae Royi sticks by her side and lets her know that she can leave, if she wants, it’s Yi-Seo who calls her up on the phone and reads her the poem, “I’m the Diamond.” Yi-Seo knows all about just being who you are and never apologizing for it to anyone for any reason. It’s a remarkably powerful scene that should give anyone goosebumps as well as something to think about.

Performances in this series are absolutely stellar with Park Seo Joon, Kwon Na Ra, and others. Still, as I’ve already pointed out, Kim Da Mi is the highlight with veteran Korean actor, Yoo Jae Myung (Dae Hee) who’s been impeccable in everything I’ve seen him in (Stranger, Strong Girl Bong Soon, Vincenzo). He brings the corporate mogul to a whole new level, and the series wouldn’t have been nearly as effective without him.

Itaewon Class is a series that should get anyone fired up to pursue their goals and dreams. It’s a marathon, not a sprint, and we see why careful planning and steadfastness are necessary ingredients as well as being willing to lean on those who want to march right along side you. It’s also a series that encourages people to always fight against discrimination and injustice no matter where they rear their ugly heads. Don’t let those with money and power call the shots. Even the smallest person can rise up and fight effectively. The mosquito is one of the smallest predators on the planet, but it also kills far more people than any other animal. Sae Royi reminded me of a mosquito. He antagonizes, pesters, and bites, forcing a reaction.

The diamond is the hardest substance that we know of, and yet it's created due to enormous pressure. But once it's created, it can withstand anything. Don't let pressure get to you. Use it! Be a diamond!

Itaewon Class feels like a series that sits nearly alone in the echelon of series that inspires and encourages us to believe in the definition of nobility: being better than you used to be. Perhaps, that is reason enough to understand why this series resonates in the hearts of so many who have watched it.
