The core theme of both stories is the same: The female protagonist possesses a vibrant personality and relies on her intelligence to survive. In different scenarios, she assumes the role of a close relative of the strict male lead. Initially, they have a competitive relationship, but gradually they develop feelings for one another. Furthermore, a second male character, an apparently perfect individual, appears as a supporting lead in both storylines.
The pairs have a similar dynamic, and there are a lot of similarities among the male leads..... plus the potatoes!
