I understand that there's only so much that can be covered in a webtoon adaptation, but as someone who's following the novel, I felt like this chapter was bit lacking.
Their secret but unplanned meeting, Navier's anxiety attack, and Heinley's shock by the sudden marriage proposal from Navier were conveyed more beautifully and described in detail in the novel, which made it one of the most memorable moments in the series.
If this chapter didn't give you enough feels, then I highly recommend you read the novel version of this scene. (Chapters 136-138 by WordExcerpt)
Still, many thanks, Majesty Heart, for your work on this! I was dying to see this translated in the webtoon.
