Longing Carved in Bone

It would be great if it was made into a TV series, I just like seeing them bickering

I like the heroine and the stepmother wants to play tricks on her as a housewife, so she directly says it openly and slaps her in the face. The part where the male and female protagonists reveal their identities to each other is a bit long-winded. The "cousin of the female protagonist" likes the female protagonist and is always causing trouble. Moreover, he and the male protagonist are brothers. This kind of triangle relationship is very annoying. Later, a "heroine's friend" and a "heroine's cousin" appeared and they thought they were a couple. It turned out that the "heroine's brother" liked the "heroine's friend" and the "male protagonist's bodyguard" also seemed to like the "female protagonist's friend". It was quite speechless. This is not a unit case. All cases are controlled by the boss behind the scenes.
