I get it. Looks like Dara final wish before her soul consumed by the snek is to do final kiss as a goodbye. She was a maiden who grew sheltered, no friend, no romance, no happiness. That's why she was bright red when calling Jurota that night. And they bumped kiss > Jurota lose consciousness.
In the first, I thought Dara covered her face because she was afraid of her monster look. Turn out she was totally embarrassed preparing for final kiss. Jurota 100% a good guy, he didn't scared looking at Dara, but sad and guilt for not noticing her ordeal.
