There’s no missing chapter! The previous chapters with the princess hinted that she had a jewel that would bring out people’s true desires more intensely and it’s implied that she used it on Hann when they met up. Which means that what his heart truly desires is Riella, hence why he seems so much more interested and expressive.
Ch 58 was about the princess coming to their country and hann refusing her, and in ch 59 hann suddenly realizes his feelings (he always liked her but before he had no idea) ???
