so often we watch often on tv. there is this father whose wife
was dead and he got a son. one day, they have a new neighbours who
is a mum who has 3 beautiful dotters.
one fine day, the son fell in love with one of the dotters and
eventually they got married. the son's father and the dotter's mum
eventually fell in love with each other.
my question is... can they get married? does this case happen in
sg? what happen if the dotter and the mum bear a child? 
Discuss pls!
