Our Blooming Youth

Crown Prince Yi Hwan is surrounded by rumors that he is cursed by a ghost. He harbors a secret he cannot reveal to anyone, and he must fight back against his enemies who plot to depose him. He meets Min Jae-yi, a woman suspected of murdering his mentor's family.

Hwan realizes he can trust no one. Jae-yi insists she's innocent and blames him for her family's death. Jae-yi knows Hwan's secret, which throws him into turmoil. Meanwhile, Jae-yi's maid, Jang Ga-ram, disguises herself as a man to seek the help of eccentric scholar Kim Myeong-jin.

Still doubtful, Hwan challenges Jae-yi to reach the Crown Prince's quarters on her own and she arrives in a way no one expects. While trying to uncover who is behind a crime, Seong-on discovers shocking evidence that his father is involved.

Hwan challenges Jae-yi to uncover why a royal messenger died. With Myeong-jin's help, she finds it is tied to Hwan's secret. Her final challenge is to solve a string of murders in the capital, forcing her to face her former betrothed, Han Seong-on.

Hwan, Jae-yi, Myeong-jin, and Ga-ram join forces to solve the case. Hwan surprises Jae-yi by hiding his identity. Seong-on gets humiliated by a eunuch. Growing tension between Hwan and his longtime friend Seong-on threatens their friendship.

After finding the culprit, Jae-yi earns Hwan's trust, and Hwan starts to believe she is innocent. Seong-on and Jae-yi run into each other, and she realizes he is carrying something related to her. News of another murder in Gaeseong throws Hwan, Jae-yi, and Seong-on into turmoil.

Unable to fully trust Jae-yi, Hwan sends her away from the palace. Jae-yi has nowhere to go, and Ga-ram risks getting captured. Hwan struggles with Jae-yi's absence, while Seong-on questions why the Crown Prince is investigating his missing betrothed.

A fierce sports match pits Hwan against Seong-on as Jae-yi watches. Meanwhile, the interrogation of the suspect reveals shocking truths that throw the palace and the capital into turmoil.

A curse throws the palace into chaos. Cho Won-bo increases the pressure on the royal family, but Hwan, Jae-yi, Myeong-jin, and Ga-ram suspect human hands are behind it. As they close in on the truth, they uncover an unexpected culprit.

With Jae-yi's help, Hwan reconciles with Seong-on and asks Jae-yi to become his friend as well. As debate over the Byeokcheon Rebellion reignites, the pair begin searching royal records for the truth.

While investigating the Byeokcheon Rebellion, Hwan questions old records and searches for the truth alongside Jae-yi and friends. As Cho Won-bo tightens his grip on the people, Hwan defies the king and faces his greatest danger yet.

Hwan relies on Jae-yi, Seong-on, Myeong-jin, and Ga-ram as he is confined to the Crown Prince's quarters. As Jae-yi recovers a crucial memory about her family's murder, she races to warn Hwan that his life is in danger.

Jae-yi is certain her memories are correct, but Hwan refuses to doubt Tae-gang. As Seong-on tracks the mastermind to Paju, he, Hwan, and Jae-yi set out together, only to face deadly danger. Meanwhile, the King meets up with someone in the dead of the night.

Back at the palace, Hwan tries to send Jae-yi back to Seong-on for her safety. Meanwhile, bounty hunters close in on Ga-ram. A gathering of the four friends turns tragic when they witness yet another murder.

A bracelet left to Jae-yi helps the group connect the scattered clues. As Hwan prepares for the royal bride selection, Prince Myeongan, haunted by nightmares, reveals a shocking secret.

The Queen is enraged to learn Cho Won-bo manipulated Prince Myeongan. Hwan seeks answers about the Byeokcheon Rebellion, while he, Jae-yi, Myeong-jin, and Ga-ram uncover another secret as they get closer to the truth.

As assassins close in, Hwan and Jae-yi question Tae-gang about a newly uncovered secret. Meanwhile, Seong-on learns Jae-yi's whereabouts, and Jae-yi risks her life while pursuing yet another crucial clue.

Seong-on is stunned to discover Ko Sun-dol is actually Jae-yi. As Tae-gang reveals his secret, the four friends search for a hidden letter that could expose the conspiracy. But an even greater danger awaits Jae-yi and Hwan.

Hwan uncovers the shocking truth hidden in a painting. Jae-yi is arrested for murder and her confession leaves him devastated. Cho Won-bo seizes the chance to demand that Hwan be deposed. Meanwhile, Seong-on receives a command from the Queen.

Cho Won-bo discovers the Queen's secret, and the Queen makes a decision. The six friends reach Naewanggol, but it's not easy getting the people to listen after many years of being ignored. Faced with another massacre like the one ten years ago, Hwan must risk everything to protect his people.
