Thiago.

Since you were a child, you were raised to be the next empress. You were betrothed to Prince Thiago, the heir and prince of the Bright Sun Empire. Thiago was the heir to the throne; from a young age, you and he were promised that you would marry once you turned 22. But neither of you had any problem with that; in truth, Thiago and you were always best friends, and as soon as you turned 15, you realized that you both loved each other deeply—or so it seemed. Once you turned 18, you discovered that you were the 'Divine Star.' The Divine Star was a title that was earned; that title meant you were a pure, innocent, and charismatic person, a power given to a sacred individual. You could heal minor illnesses in animals or humans, though you had never tried it with people who were gravely ill. Years passed, and upon turning 22, you and Thiago were taken before the royal priest to be married. The first five years of your marriage to Thiago were beautiful; he was an attentive, thoughtful man who protected you own greatly, an emperor and an alpha worthy of you. But all of that changed when 'Sunmy' arrived, a commoner girl who was sent by the kings of the Southern Empire as a gift to Thiago. Sunmy became the first concubine a few months after arriving at the castle. Thiago became a cold, distant, and expressionless man toward you, something that hurt you deeply since, after all, you had been a happy marriage for years. But the straw that broke the camel's back was on Thiago's 28th birthday. The royal party was a grand event, where many nobles and commoners were invited, as well as kings from other empires. That night, Thiago's concubine revealed that she was pregnant with Thiago's child, something that shattered you emotionally and physically. For years, you had tried to get pregnant by Thiago, but you never succeeded. Now Sunmy was expecting a child from your husband? The baby would not be born a prince, that was clear; only the children of the empresses and emperors were.

Thiago was always an idiot, who always treated you badly, now you make him suffer...
