The Three Musketeers

Park Chi-won, visiting Yun Kyung, finds a rusty book written, "Park Dal-hyang's Life" at a huge library in a Forbidden City. The main character, Dal-hyang comes to Hanyang after passing the exam to marry his first love Yoon-seo. Then there, he meets the Three Musketeers.

After the arrival at Hanyang, Park Dal-hyang has his first encounter with the Three Musketeers. With Sohyun's help, Dal-hyang closely passes the exam. Afterward, Dal-hyang's first love Kangbin, shows up. Meanwhile, Seung-po and Min-seo, who came to buy a congratulatory drink for Dal-hyang, spot a shocking scene.

After seeing Mi-ryung, who Sohyun thought was dead, he demands a thorough search through Mi-ryung's death again. Meanwhile, Dal-hyang, who passes the exam, heads to Bang Bang Eui. However, there, an unexpected person shows up.

After receiving an order to find Mi-ryung, Dal-hyang sneaks into the envoy's residence and finally faces Mi-ryung. Meanwhile, Kangbin, who does not have an heir, receives a talisman from her mother to bring luck for conceiving a child. Then Sohyun, who has always been cold to Kangbin, says that Kangbin should stay awhile.

Dal-hyang aims at Yong Gol-dae as the King demands, but Seung-po and Min-seo rush over to protect Yong Gol-dae as Sohyun demands. Meanwhile, someone visits Kangbin while she is anxious about Yeon-seo.

Seung-po teases Sohyun that he is jealous of Dal-hyang. This prompts Sohyun to challenge Dal-hyang to another duel. Meanwhile, someone changes the lock of the library Yong Gol-dae is in, and Dal-hyang chases after the spy that caused such chaos.

After seeing Sohyun bleed from being stabbed by Mi-ryung, Dal-hyang rages with anger points his sword at Mi-ryung, but Sohyun demands him not to and actually protects Mi-ryung. Meanwhile, Kim Ja-jeom heads to the palace when he does not receive any answers from Sohyun.

Mi-ryung sneaks into the palace to see how Sohyun is doing, but Kangbin spots her and quickly chases after Mi-ryung. Meanwhile, someone shows up in front of Dal-hyang at night after his rough time at the royal prison.

Sohyun explains that he cannot let Kangbin leave the palace, and Kangbin feels suffocated from this, so she gets drunk out of anger. Meanwhile, Dal-hyang visits Yong Gol-dae to learn more martial moves, but Yong Gol-dae turns violent and tries to kill Dal-hyang.

A knife is thrown exactly where Dal-hyang is hiding, underneath the floor. Dal-hyang falls into the danger of death once again. Kim Ja-jeom shows Dal-hyang's neck to Sohyun, Seung-po, and Min-seo. This shocks and infuriates Sohyun, so he punches Kim Ja-jeom.

After turning Kim Ja-jeom's scheme into a bubble, Dal-hyang gets recognition for his work and receives a promotion. Meanwhile, Sohyun, who has not been at the palace for a long time, returns and heads to the palace excited to see Kangbin, but Kangbin only compliments Dal-hyang who safely brought the hairpin.

Kangbin gets a severe injury from the arrow Mi-ryung shot, and Sohyun infuriated, goes to end Mi-ryung. Meanwhile, a letter flies in after Dal-hyang wraps his father's funeral.
