Well the other son gave them a grandchild so he's done his duty
Not quite. With these types lf parents especially some Asian parents they are adament about marriage and having grandkids. And if their kid is divorced with a kid they will make a fuss about how they need a wife in their life because how can they possible take care of themselves without the help a wife to basically be a free housekeeper to them to take care of all their personal needs. Not to mention, they love bringing up how their grandkids would be "so unhappy without a mother" or if it were vice versa it be their father.
I feel like with the mom finally coming around, its going to get real boring. OMG what are they going to do when they find out their other son has a been too? I want a deeper story with the brother and the friend. Im all caught up on this so far.. its so cute!
