Schean Tseii Santiago, or simply Ean-Ean Santiago, is the famous "Resident Bad Girl of Arsenal High." Smart, beautiful, rich, and super sexy, count in the fact na nagkakandarapa ang mga lalaki sa kanya. Sabi ng iba, sayang daw at bad girl siya, since she's a catch. But nobody knows that there are more things na tinatago ni Ean-ean. Hurting from a breakup, from Collins' High, she transfers to Arsenal High, with the promise of not falling in love again. There she meets Crystal Katherine Sanchez, the "Good Girl of Arsenal High." They become fast friends, even though they're the total opposite of the other. Pero ang inaasam na calm highschool life ni Ean-ean ay magbabago nang makilala niya si Sean Tristan Acosta, ang leader ng top gang ng Arsenal High, ang Arsenal Gangsters. Hindi magkasundo si Ean-Ean at Sean, pero napapalapit lang sila dahil gagang inlababo si Crystal kay Sean. Pero let's fast forward na. Nagkaroon ng mga away, selosan, iyakan, tawanan at iba pa. Pero makukuntento na kaya ang tadhana na paglaruan si Ean-Ean gamit si Sean, or is there something fate has up to its sleeve? Matatahimik pa ba kaya ang buhay ni Schean Tseii Santiago, or will Sean Tristan Acosta be the guy na matagal nang pinapangarap ni Ean-Ean, someone who understands her? Will the present remain present and the past be just past, or will the past jump to the present and propose another challenge for them? Will all hell break loose, or will the heavens celebrate for joy, when the Bad Girl meets the Bad Boy?

Ang kwentong ito ay isang katotohanan na may halong kathang isip din :)
