As the final pieces of Dong-eun’s revenge plot slot into place, she considers what comes next — and what it will mean for Yeo-jeong.

Do-yeong issues an ultimatum. Dong-eun demands a piece of evidence be handed over. Yeon-jin attempts to do damage control after old videos appear online.

Dong-eun’s end game comes into focus as she sends Jae-jun a troubling package and orchestrates a plan to take down Yeon-jin and Lee Sa-ra.

Hye-jeong finds an incriminating recording on Myeong-o’s tablet, and Hyeon-nam receives an unwelcome visitor as she prepares to send her daughter abroad.

Son Myeong-o’s sudden absence causes tension in the friend group. Dong-eun finds her trust in Kang Hyeon-nam tested.

With Park Yeon-jin’s wedding on the way, Dong-eun’s revenge rolls out according to plan. Meanwhile, a fateful encounter at a hospital takes place.

Tormented by her high school classmates and with nowhere to turn for help, Moon Dong-eun sinks into despair before deciding on a new mission in life.
