Family love

Rosalyn's (FL) family is full of love; the parents love each other and their kids, and the siblings love each other and their parents as well

Rosé's family is really tight-knit. She's especially tight with her brother Hans and her parents. Her parents love and treasure each other as well as their children which is rare in these types of stories

The ML is very close with his family, which is very refreshing and adorable. His father is especially sweet and supportive; it's not common for a typically cold ML with "devilish origins" to not have awful parents, conniving brothers, or an evil stepmom. FL seems to have been close to her mom as well
