Hindi ko alam kung maniniwala ba ako na mayroon daw na pagala-galang tao na may lahing ahas. Ewan ko ba kung totoo na nangangain slash kumakain din sya ng mga tao. Hmp. Siguro galing lang 'yun sa mga chismis na nagpasalin-salin sa mga tao. Pero what the fork?! Bakit nasa harapan ko sya ngayon? At bakit ang sama ng tingin nya sa akin? Infairness, ang ganda nya ha.

Chung Soobin used to have a harmless crush on her best friend, Hyewon-until she met Hyewon's older sister. Professor Lee Hyeri was everything Soobin thought she didn't like: arrogant, clingy, and annoyingly persistent. But the more Hyeri clung to her, the more Soobin found herself drawn in... until it was too late to pull away. Because Hyeri isn't just in love-she's obsessed. Manipulative, possessive, and dangerously devoted, she's willing to lie, hurt, and kill to keep Soobin by her side. And while Soobin starts to fall, everyone around her starts to worry-especially Hyewon, who quietly hides her own feelings for Soobin while watching her slip deeper into Hyeri's grasp. Soobin thinks she's in love. But what if love is the most dangerous thing of all?
