Y does anybody have to break up?

If the parent get married then they will be stepbrothers. And two siblings sleeping together step or not especially boys makes the family look bad, and they have to care about appearance because they both run large companies. Plus if he did marry her he’d have to choose between having a wife the family doesn’t want and his son.

Nope. It still doesn't make sense. There are many types of family in the world. In my culture n religion even if parents remarry it is possible for step siblings if of adult age (before the parents marriage) can marry each other. N talking abt the corporate lives of these characters there is no involvement nor a hint of involvement of children in their parents lives. Each lives their own life whether it is in a room infront of the computer, owning a hair salon or living abroad. So i dont see why thy cant continue to do so. Cuz all anybody is ever looking for is a person with whom thy can be happy or someone who makes them happy.

I mean cool but most people will find that disgusting and it is probably socially acceptable. This shouldn’t be normalized in real life though. I do hope they all become happy but I just couldn’t be in this situation and everyone come out happy.

Ok
