Lee Bo-young was fond of knowing Kim Seo-hyungg's Secret
In the 15th episode of TVN's Saturday, Drama 'Mine' (played by Baek Mi-kyung/directed by Lee Bo-young), which was broadcast on June 26, Seo Hee-soo knew the Secret of Kim Seo-hyung.
Han Ji-yong (Lee Hyun-wook) angered his wife Seo Hee-soo a day before her death, saying, "Seo Hee-soo, Jeong Seo-hyun, do you think you can ruin me? You did this by turning the video of Lee Hye-jin (Ok Ja-yeon)?"
Seo Hee-soo said, “I just stopped Hyo-won from being the representative. That’s not all. You’re disqualified. You killed people. You going to police tomorrow? “Hyowon’s legal team will not help you. Show him your best father for him. Confess and acknowledge all sins.”
Han Ji-yong said, "You want to ruin me, you want to take Ha Jun-yi, and Jeong Seo-hyeon wants to take Hyo-won. Neither can. You, who didn’t mix a drop of blood with Ha Jun-i, and the Sexual minority, Jeong Seo-hyeon, will not have Mine either. No, not before I die.”
Seo Hee-soo heard Han Ji-yong and found out that his brother, Jeong Seo-hyun, was a Sexual minority. Seo Hee-soo remembered that Jeong Seo-hyun said, "I did not have a boyfriend but I had a lover."
