Mob character watches the main girl fish for a male lead (the fishes). Starts a popcorn business; her shenanigans catches one of the fishes interest (bloody tower master); Writes BL books and has a princess as a fan. People's names are funny - they are based on what the character does instead of being a real name.
Thank you so much, but I meant the blonde prince and brown haired gurl in the new chapter?
The brown haired girl is Latte and the blonde prince is the prince of the kingdom she is currently in (brown haired girls hometown). The brown haired girl made a wish to become the most beautiful girl and ended up swapping bodies with Latte.
It's been so long, may someone remind me who they are #－.－)
