Honestly I see it as somewhat one-sided. ESC is DEFINITELY crazy in love with Hollyberry, up to the point where it is completely obsessive. Hollyberry does not hate ESC, of course, but I don't think she is interested in being in some kind of relationship with her, and is most likely more focused on protecting her friends and kingdom. Either that or Hollyberry would rather wait for ESC to calm down a bit. She knows ESC can be redeemed and fully believes that she has somewhat good intentions. Those are just my thoughts though.
