It's now been a month since Dr. Jinsoo left, and the doctor's assistant, the director, is waiting for him to return. The director says that he hasn't had sex in a month because he's in such a bad shape. He tells the doctor that his sex drive is getting stronger and stronger, and that he'll have to "suppress" it if he wants to have sex with her. He says that even though he blocked the "yin energy" for now, it could "explode again" at any moment. He asks the director to come back and tell him what's going on, because he has something to tell him. He's here to fill him up with energy.
