Needing work to support her family (thanks to Hee Soo's machinations), Jan Di unwittingly falls within grasp of exploitative pornographers. Fortunately, an unnamed rescuer appears just in time. Back at school, new student Jae Ha introduces himself to Jan Di as her fan and supplies her with part-time work at a proper modeling studio. There she learns that student Jae Ha and the mysterious supermodel Haje (her earlier rescuer) are one and the same. Concealing her need for employment from Joon Pyo causes her to lie to him, frustrating Joon Pyo and leading to their breakup. While both Jae Ha and Ji Hoo stand ready to become her boyfriend, Jan Di gets an F4 red card. It's the first time a student ever got selected twice to be hazed, but the new attacks become life threatening. It turns out there's a serpent at work behind most of these recent doings, and both Jan Di and Joon Pyo are at risk.
