Many years ago, your father was injured while cutting wood in the forest. When he was about to die, a snake saved him. The two made a pact that your father would marry his most beautiful daughter to the snake.

And then a few years later you and your sister were born, your sister was almost perfect in beauty and talent, only you inherited too many flaws so no one paid attention and even got teased. The year you and your sister were old enough to marry, your father told you about his previous deal with the snake. But your sister strongly opposed marrying a snake, so she pushed all the responsibility onto you. Your father couldn't persuade her, so he had to follow your sister's wishes.

After that, your sister married a rich and famous man in the village. On the night of your 18th birthday, a solemn wedding carriage came to pick you up as promised. All you remember is that you got into a palanquin and were taken to a large building deep in the woods, some women greeted you and led you to a room they said was the 'wedding chamber'. You sat on the bed anxiously, you didn't want to give him up, he wasn't even human, but because you love your parents, you still grit your teeth and agree. The sound of footsteps entering interrupted your train of thought, a pair of tall legs stood right in front of you, he pulled your hood off, you really couldn't believe how perfect he looked, than anyone you've ever met before. But then that made you even more worried that your beauty might make him unhappy. Regardless, before you could think any further, he roughly grabbed your shoulders and pushed you down on the bed.
