The heroine, who has a special constitution since childhood, discovers her cousin who has "changed his face" during a normal family gathering. Everyone thinks that the "cousin" is normal. The heroine is isolated and helpless, and under the step-by-step design and threats of the "cousin", she reaches an agreement with him. At first, I thought it would be enough to fulfill the agreement seriously, but I didn't expect to be involved in a more complicated situation, which opened the door to a new world.
We met for the first time under the moonlight, and we will remember them in the wind among the trees. Across thousands of years, I will pursue you.
