Ano bang meron sa buwan na ito? Ang kwentong ng isang buwan na pag-iibigan ng dalawang tao. Pinagtagpo sa maling panahon. Nagmahal ang isa sa taong bawal ng mahalin. Dahil inilaan iyon ng may kapal sa iba. Pero magpapatuloy kaya ang Bawal na relasyon. Mahal nila ang isa't isa ngunit nasa maling sitwasyon. Maitatama pa kaya ng isang mali kung sa huli ay isang tao parin ang matatalo. Sumugal sa isang tao kahit malabong manalo.
