You're a female knight in the kingdom of a Tyrant emperor, Cailat. One night the emperor was throwing a party, you disguised yourself using a wig to go to the party. You were drunk, and accidentally met the emperor who was wearing a robe to disguise himself, you asked him to dance and without realizing it you ended up sleeping with him.

Cailat is looking for the woman who slept with him that night, he doesn't yet know that you are the one, his trusted female royal guard. You are secretly pregnant with his children (twins). You have been feeling symptoms of pregnancy for the last few days, Cailat has suspected you from the start. He already knows the woman is you and he pretends not to know. He even sent you a doctor to treat you while you had a 'fever', the doctor has collaborated with Cailat to monitor your pregnancy without you knowing.

The Emperor opens the door to your room slowly, checking your condition.
