Other than Park Eun Bin, Kang Tae Oh, Kang Ki Young and the rest of the supporting stars, the brief appearances of many popular stars truly made "Extraordinary Attorney Woo" a great drama.

Here are the different actors who shared unforgettable moral lessons through their remarkable guest appearances!

Shin Ha Young

Shin Ha Young recently appeared as a jinxed bride whose dress slipped off during her much anticipated entourage in her wedding in "Extraordinary Attorney Woo."

Due to the commotion, her father tried to sue the wedding venue, which prepared the wedding dress beforehand.

The unlucky wedding became sensationalized news as everyone made a big deal out of it. It turns out, the dress was a bust from the get go as it was swapped with another dress by the staff.

At the end of the episode, the bride withdraws the lawsuit as she just wants to live a happy life with the person she loves: a woman who has been by her side forever, her girlfriend.

Shin Ha Young's appearance didn't only create buzz for the unconventional story, but also because of its awareness to the LGBTQIA+ community.

Moon Sang Hoon

Moon Sang Hoon played the role of an autistic character in the drama. He was accused of killing his older brother, and his wealthy family wishes for him to be exonerated due to insanity.

Thankfully, attorney Woo Young Woo (Park Eun Bin), who's also an autistic person, just knows how to solve the case.

The actor's performance as a disabled person brought viewers to tears, especially when it was revealed how much he loved his late older brother.

In particular, his guest appearance heralded the popular clip of Woo Young Woo and the Hanbada lawyers singing Pengsoo's penguin song, singing and dancing together.

Koo Kyo Hwan

"D.P." starrer Koo Kyo Hwan is perhaps the most loved guest character so far. In the drama, the actor played the role of Bang Gu Ppong, the Commander-in-Chief of the Children's Liberation Army.

Instead of taking the students to his mother's academy, he drove the bus and took the kids to a picnic for them to relax and have fun, which was the sole reason why he was accused of "kidnapping" the young students.

Not only did he touch the viewers' hearts, but he also successfully delivered the message of liberating oneself through making time for self-care and freedom.

Viewers, who were able to relate to the story, listed Koo Kyo Hwan's appearance as their most favorite episode yet.

Seo Hye Won

Known for her roles in the dramas "Nevertheless," "True Beauty" and "A Business Proposal," Seo Hye Won wowed fans with her transformation as a mistress in the court romance drama.

Seo Hye Won was the other woman of a man who won the lottery in "Extraordinary Attorney Woo," who showcased a different side of her.

This year, the actress made dramas trend for her quirky performances. In fact, her scenes in "A Business Proposal" topped the Twitter and other social media apps trends.

At the moment, the actress stars as a swindler who pretends to be blind in Jung So Min and Lee Jae Wook's fantasy drama "Alchemy of Souls."
