That scene also seems kind of foreshadow-y for some reason, don't know.
Too agree that those scenes look too mesmerizing compared to Adini's. It doesn't seem like Sugni's heart skips a beat or anything like that when Adi tries to romance with her. Don't think she really has strong feelings like those for Adi... as like some members said, she probably has Vickram deep in her heart still... or that her romantic self is sort of dead after all that happened with Vickram (how she felt deceived by him). just guessing possibilities !
Also, I really loved the metaphor about security blanket. I think it's true. And, I think she's attracted to affection and kindheartedness. could be a good and bad thing.
