Sinteya Yeo has always been into "sinful" acts until her world was shaken when she took the challenge of playing fire with her respectable college professor. ***** Pinaniniwalaan ni Sinteya Yeo na sex objects lang ang tingin ng mga lalaki sa mga babae, a belief borne from the fact that she's the daughter of a single mother and unknown father. Kung sex lang ang habol ng mga ito, then sex lang ang ibibigay niya and nothing else. That view in life molded the woman she is today until she sets her sights on her handsome ethics professor, Sir Marco, who brushes off sexual innuendos and flirtations.
