Well I'm way farther back than you guys, but from what I understood so far, CDH's father's legal wife went off to America to have a child, right? And that CDH's grandfather seemed to love his daughter-in-law more than his own son, which is probably why the grandmother prefers their son instead. Anyway, the grandfather and legal wife died in the car accident and the father "died" in the fire. I always wondered if the child the legal wife bore was her father-in-law's or her husband. Or is it another man's? It seemed so complicated and confusing that I fairly gave up trying to understand it.
