Han Ji-min went back to the past 12 years ago and became a high school student.
On tvN 'Knowing Wife' broadcast on the 12th, Woojin (Han Ji-min) became a high school student and opened his eyes.
Woojin met common sense straight to college, and there was no Woojin in the memory of common sense, but she insisted that she should meet Juhyeok.
On the way to see Ju-hyeok, however, Woojin faced Hye-won (Kang Han-Na). Woojin's expression was not good.
Ji Sung, who heard from common sense, hid himself from Woojin, but Joohyuk was in the hands of Woojin.
