Alvin falls in love with Kristine (Shaina Magdayao), a rich and talented girl who lives under the strict hand of a very influential father (Tirso Cruz III). Can love survive the odds? Will Alvin fight for his true love? Will the man get to keep his romance with the man? Will everybody's hearts indeed be happy?
