These two guys had a grudge to a man, an eternal villain, who had made their dreams be never reached ever again. They had planned to 'attack' the villain by using the villain's only daughter.

A woman, the villain's only daughter, was looking for a 'victim'. She kept looking and looking until she finally found one, or two, actually. The two guys came to her hiding spot, unexpectedly. She was ready to 'attack' these guys.

Who survived at the end?

Or would anyone actually make to survive? As the 'attack' was not about a physical attack. It was a mental attack.

It was related to an attack to the organ which was sensitive enough to women even men.

The heart

which determined whether a single person was in love or not.
