In episode 21 of the KBS 2TV daily drama 'Trap of Desire,' two key pieces of evidence—a fabricated suicide note and a maternity notebook—emerged, once again bringing the hidden pasts of major characters to the surface.

■ Go Eun-seol clears her name through the fabricated suicide note, but suspicions of a mastermind persist

At the center of this episode was Joo Mi-ran's meticulous scheme. To conceal her identity, Joo Mi-ran eliminated Manager Na and even fabricated a suicide note for Go Eun-seol. The note contained a statement that Manager Na had killed Park Hee-jung, which became the basis for Go Eun-seol being cleared of the murder charge.

However, Go Eun-seol did not rest easy. She questioned the fact that there was no connection between Manager Na and Park Hee-jung, continued to suspect the possibility of another mastermind, and did not stop her efforts to uncover the truth of the case.

■ Unyielding despite demands to resign... Tensions rise between Go Eun-seol and Joo Mi-ran

At the company, Go Eun-seol was depicted rejecting Kang Hae-ra's demand that she resign and vowing to prove her abilities. Later, at a meeting with Joo Mi-ran, she refused to accept consolation money and directly raised the still-unresolved issues of the retrial and Lee Jung-tae. When Go Eun-seol left the seat, Joo Mi-ran's expression hardened, heightening the tension between the two characters.

■ 'Joo Ae-sook' in the maternity notebook... A new clue to the secret of Go Eun-seol's birth

The biggest twist of the episode came from Park Hee-jung's belongings. While organizing her effects, Ko Ki-han and Wang Geum-ja discovered a maternity notebook with a date matching Go Eun-seol's birthday, in which the name 'Joo Ae-sook' was written. This discovery raised new questions about Go Eun-seol's birth mother.

Adding to this, a scene showing Joo Mi-ran suffering a nightmare that appeared to stir memories related to childbirth has heightened curiosity about how the story will unfold.
