Why did South Korean billionaire Chey's ex-wife get ₹6,200 crore in 'divorce of the century'?

A South Korean court awarded SK Group's billionaire Chairman Chey Tae-won's ex-wife, Roh Soh-yeong, 944 billion won (over ₹6,200 crore) in a divorce settlement. The court said her homemaking and childcare contributed to the couple's wealth, entitling her to one-third of their marital assets. The case has been locally dubbed the "divorce of the century".
