I squealed a lot during this episode.
The experiment gets wrapped up. Zen and Shirayuki have an important moment in the tower. Zen escorts Kihal back to her island home and secures their good will.
Zen comes back to the palace and Shirayuki runs away from him.
And then they have more important moments.
This made me so happy. There was discussion of consent and feelings and what the two of them want. Cute and wonderful.
