The features of this tea party town are entirely in Lianna's personal style.
Whether it's the rose scent, the rose carvings, or the occasional falling rain of rose petals, they're all emphasizing Lianna's personal traits.
This is understandable, after all, Lianna is the organizer of this tea party. Since she is hosting, it makes perfect sense for her to design the tea party town with a "rose" theme.
However, if this rose-themed town is to be moved to the Wilderness of Dreams, there would be some issues.
It's not that the Wilderness of Dreams cannot embody Lianna's personal style, but focusing too much on personal experience will naturally restrict the scope, in Angel's view.
After all, Angel intends to use this tea party as the beginning to gradually unveil the Wilderness of Dreams in the Southern Domain Wizard World.
It can be said that the main purpose of this tea party is to inaugurate the Wilderness of Dreams.
