"You worm-like thing." That was what Yeon always heard from her master. Yeon's master was the Azure Dragon, the guardian deity of the East. A pureblood dragon who valued lineage above all else. "You know you'll die instantly without me, don't you?" A water snake's lifespan is only about 10 years. The reason why Yeon, who should only live for 10 years, has lived for over 100 is because the Azure Dragon shares his life force with her. As Yeon, who would die immediately without the Azure Dragon, she has no choice but to serve this Azure Dragon well, whether she likes it or not. Then one day, an unbelievable thing happened. While undressing the heavily drunk Azure Dragon, Yeon ended up being completely devoured by him. Of course, it happened while he was intoxicated, so this damned Azure Dragon doesn't remember. Yeon, who received a favor that the giver doesn't even recall. What should she do? If the pureblood Azure Dragon finds out that a worm, no, a water snake, received his essence and even got pregnant, he will try to kill her instantly. What should she do? She has to hide it. She has to hide the fact of the pregnancy and the favor. But the more she hides it, the more the Azure Dragon becomes suspicious of Yeon. "Whose child are you carrying?" Finally, Yeon's pregnancy is discovered...!
