Neoma Belmonte is the only child of the internationally renowned business tycoon Wile Belmonte. She and her father have a love-hate relationship ever since her mother left them. She may have her mother's looks, but she certainly inherited his father's sadistic psyche. Years passed and she grew up to be a goddess. Things take a crucial turn however when her father forced her to marry the son of his friend. From her rebellion came his decision to start the "Marriage Game." He has her face broadcasted on national tv, and he announced that whoever is the man who can bring her back home will be entitled to marry her and inherit his entire fortune. How will she and Sol and Owel, the two men who willingly became her loyal dogs, help her liberate herself from her father's manipulation?

13 years...It has been that long that Noumenon has been away from Intramuros--the place she never wants to go back to. However, as a novice who is assigned to do a field observation there, she is left with no choice but to enter, again, the walls of the very city where she witnessed how her own father murdered her mother. She thought that she only has to deal with that harrowing memory, but it turns out that Intramuros has plenty in store for her--from criminal masterminds, individuals with divinities (supernatural abilities) to the most notorious masked vigilante named "Cross" the "Master Murderer." Her initial plan to live in a cloister for the rest of her life is postponed as she is entangled in conflicts which will bring her suffering and enlightenment and will stir the long dormant emotion within her: madness. This is the tale of a girl named "Noumenon" and this is not for the faint of heart.
