I lost my innocence to the underworld King

I lost my innocence to the underworld King belongs to the new wave of vertical dramas: a contract marriage and romance story framed tall and cut into bite-size episodes. Like most vertical dramas, it moves fast: short episodes, a cliffhanger at the end of each, and no filler. Read the synopsis below, then jump straight to episode one.

Country girl Sophie travels to Athens seeking help to save her critically ill grandmother, only to be betrayed by her boyfriend and stepsister. Hades, King of the Underworld, marries her on the condition that he heals her grandma. The two fall in love after marriage, and she ultimately becomes the Queen of the Underworld.
