Shaina is a member of the group of gangster , pero dahil nainlove siya sa Math Club President nila, she decided to quit and be a good girl instead. Isang gabi , she saw a nerd na lalaking hindi niya kilala pero iniligtas niya mula sa mga grupo ng lalaki pero laking gulat niya ng Sabihin ng leader ng gang na : "YOU'RE MINE SWEETY. TRY TO ESCAPE FROM ME, AND ILL ASSURE YOU ONE THING,, YOU'LL STILL FALL IN MY HANDS, OR BETTER YET , IN MY BED" oh god! I'm in big trouble, the gangster is in love with me... And why is that na parang magka boses sila ng School Math Club President nila?!!!!!!!? And,,,why is that , her heart is beating so loud na parang lalabas na ito sa dibdib niya!! Oh my god! I'm in trouble, I'm in love to a different person at the same time.
