I've read some spoilers from the novel and essentially what happens in the date is that they visit places, then when they went to the temple of raulus, yeni hears raulus's voice in her head and they become friends kinda lol their interactions are cute. Then soleia had casted black magic to make yeni have nightmares for her to die in her sleep. So yeni kept getting nightmares idk for how long. But cause she doesn't rmb the nightmares, she just brushes it off. Every morning she wakes up in cold sweat and is pale. The maids were worried and brought the doctor but the Dr said she was in good health. One day yeni bumped into soleia again and soleia was like "you look bad, did you have a nightmare?" And yeni got suspicious. Then soleia increased the magic around the palace. That night yeni's soul as her Korean persona came out of her body and saw yeni dead. And raulus told her to quickly enter back into her body otherwise she will die for real. So she did, and she woke up. She ran away from the palace in fear but it was dawn so she didn't know where to go but remembered that eru did his morning practise at the training grounds so she ran there. Eru saw yeni pale and running so he hug her and she said bellrock palace has been weird and eru understood what she meant. She fainted in his arms and he brought her back to his main palace. She wasn't allowed back into bellrock thereafter, and stayed in the main palace
Take it with a grain of salt, this was what I read from other people who had MTL the novel / read it ages ago
but it was so cute and I absolutely wanted more!! I can't wait for author-nim to draw this scene
