Can you recommend a novel about an overbearing CEO?

I forgot the names of the male and female leads. The male lead has manic disorder. The female lead and the second male lead are cousins. Because the female lead is not his biological child, she was chased out by her father's family. Her profession might be designing. The female lead met the male lead after being drugged and then lived in the castle of the male lead's family on the mountain. There was a plot where the male lead misunderstood the female lead for betraying him and became manic. Then, he chased the female lead. The female lead hid in what should be a warehouse and then left. There was also a plot where the female protagonist was kidnapped and had a mental breakdown after being rescued. The male protagonist asked the second male protagonist to take the female protagonist away.
