i don't know yet if the prince found her because i haven't finished the translated novel but her brother did find her. However, that scene is far from where the manga left off so there's still a lot of chapters to go before it will be drawn.

where did u read the novel? can u send the link please?

start reading somewhere on volume 1 chapter 7, i forgot what part it is but it's around there that the manga left off

The prince and the brother did found her later. Prince wanted her to get back to him cause he’s an a-hole and the brother got mad at her because of ‘ruining their family’s reputation’ so Shize-san sheltered her to hide from her bro later...
