I just started watching ROCH 84 (again), I just noticed something I never bother to know before:

What's the relationship between Wu San Tong (Wu brothers' father) and Lu's wife (Li Mou Cou's rival)? The Indonesian translation said Wu San Tong is her stepfather. But I sense something deeper than that. I mean why would Wu San Tong dug her grave after all those years of separation?
It also doesn't make any sense how Lu's wife doesn't look so much younger than Wu San Tong to be her stepdaughter. Looking at Wu San Tong's own sons, they're still very little. So much age difference between them and Lu's wife?
But if it's "love", turned out that he's married and have two kids now. Why is he still obsessed with Lu's wife?

And why was Wu San Tong against the marriage between the two? Surely he's not a friend of Li Mou Cou?

I'm still on episode 1, so I might have more questions later
