He stars alongside Kim Hye-yoon who plays Kim Jo-yi, a divorced woman who travels to local provinces undercover to pin down corruption.  The two decided to work together to solve crimes but end up changing each other’s lives for the better. 

The Secret Royal Inspector and Jo have gained popularity for their refreshing and feel-good comedy. However, it’s also another revelation to Taecyeon’s versatility in acting. The rapper singer-songwriter has crossed over to film and dramas with an impressive filmography that dates back to 2010. He debuted in the KBS drama series, Cinderella’s Sister and went on to join other k-pop idols in high school drama, Dream High.

Headlined by Song Joong-ki as the titular character, the series is about a consiglieri’s efforts to recover 1.5 tons of gold stashed underneath a building in Geumga Plaza. 

Taecyeon plays Jang Jun-woo, a nerdy intern in the Wusang Law Firm. However, his happy-go-lucky, dumb, and quirky character all turned out to be a front. Jun-woo turns out to be the series’ biggest plot twist. 



Imitation is a K-drama that will interest a lot of K-pop fans as it gives us a sneak peek into the glamorous and inspiring lives of idols in the entertainment industry. The webtoon-based drama is actually an underdog story that also delves into the secret romance between a member of a rookie girl group and a member of a famous boy group. What better to fill these roles than actual idols! Among them are Chani (SF9), Lee Jun-young (U-Kiss), Jung Yung-ho (Ateez), Park Ji-yeon (T-ara), Choi Jong-ho (SF9), Park Seong-hwa (Ateez), and Lee Soo-woong (Boys Republic).

Another entertaining feature of this drama is its soundtrack. Expect good and catchy songs, recorded by the idols themselves. Production even went so far as creating social media accounts on Instagram and Twitter for the different groups in the show. They produced special content related to the characters as if they were real groups!

The two ended up participating in a TV show where they have to live together for an extended period of time. 2PM’s Hwang Chan-sung also joins the cast as Choi Jae-joon, a chaebol and the CEO of an entertainment agency. 

Even though the series comes with quite a few drama tropes, they still draw in fans with their visually stunning cast, realistic characters, rich stories, and exciting K-pop performances!



Snowdrop is a k-drama that blinks have been anticipating as it stars Blackpink’s Jisoo in her first starring role alongside Jung Hae-in. It is a period drama and political satire about the corrupt powerful circles of the time.  Also involved in these political troubles are young people who fell victims in the fight for power and money, which resulted in the 1987 Gangju Student Uprising. The story follows Eun Yeong-ro (Jisoo), a student at a women’s university in Seoul. Her life took an unexpected turn when a strange man (Jung Hae-in) arrived at the university all covered in blood. They got into a forbidden relationship that puts them both at risk due to a dangerous secret that could threaten the country.

However, the drama soon faced controversy over its portrayal of a sensitive period in history.  They got a lot of criticism for distorting history by turning real-life protesters into North Korean spies and putting the secret police in a positive light. Some 300,000 Koreans even signed a petition to end the series. But JTBC stood firm, and if you don’t mind some inaccuracies and take it as creative license, you can enjoy the story in its entirety on Disney+.
