“A wedding, yes, but not to this girl. You will go down because of this. I would make you pay a million times over. This is my promise to you.”

Being drugged and unknowingly having a one-night-stand with a stranger, Andromeda Kai found out that losing her virginity was not as painful as being cheated on by her fiancé and co-designer a day before her wedding.

Even with this setback, she refused to cower. She would repay her enemies’ schemes a hundredfold and stop at nothing till she stands on top of the fashion world!

She is prepared to do it alone - but she gets help from someone unexpected!

With the tale of a sweet romance hanging around her life, demanding her love and attention, Andromeda is

confronted on all sides by the undying love of Liu Xueyi, the entertainment emperor, who would use all means to make the queen of the fashion world fall for him.

So many secrets lay in the dark while her enemies try to steal her glory, ruining her completely.

She had her plans. He had greater plans for her. He would make her rule and bring her enemies down, not as a queen but as an Empress!

For He Yi, life was like a coffee table laid with all sorts of coffee mugs resembling her misfortunes. She lost her virtue and had a premarital pregnancy—without knowing the father’s identity—right before her engagement. Her father passed away due to a heart attack when his company wound up. At that point, He Yi’s child was one-month-old and the culprit behind these tragedies was her trusted husband.

Under despair and rage, she drove toward her nemesis to knock him down. That had resulted in her becoming a destitute divorcee who could not afford proper meals after she had finished serving her sentence in prison five years later. She lost everything and her child was snatched away by her nemesis.

Her ex-husband eventually married his mistress who was contemptuous of her. “How are you able to live with this? I’d die much earlier if I were you.”

He Yi only gave a slight cold smile. “The reason I’m still alive is to witness how you go to Hell!”

This is a story of a little man who walks forward silently, in awe, and strives to chase his dream.
