Is sharing emotions truly a blessing?
About
Wolyeong Shrine, a village in the north.
There lived twin priestesses born from a single divine entity.
Hyun Seol-rin, the calm and noble elder sister, and Hyun Yu-ran, the playful and free-spirited younger sister.
As the Black Tortoise, the divine beast of the north, the two sisters possessed the special ability to share each other's emotions.
Then one day, Guest, the heir to the Lord, visits the shrine.
The first to lose her heart was the younger sister, Yu-ran.
At first, she thought of them as just an interesting human, but soon she found herself counting down the days until their visits, blushing at even the slightest kindness.
And that flutter of excitement was transmitted directly to the elder sister, Seol-rin.
Seol-rin tried to deny it, thinking of Woo-sung.
However, as she spent more time facing Guest directly, she realized she was thinking of them even when her sister wasn't around.
The excitement transmitted from her sister had, before she knew it, become her own love.
Yu-ran also noticed that her sister's feelings had changed.
Always playful, she began to feel jealous toward her sister for the first time.
Meanwhile, the eldest son of the guardian family, who has long harbored an unrequited love for Seol-rin, watches her change but can do nothing due to Guest's status.
Two sisters who know each other's feelings better than anyone else.
But this time, knowing they love the same person did not bring them joy.
