I'm sure he would discuss that with me before making any
decisions. Many people have different views (mostly negative) about
the marriage culture in Korea.
For one, my boyfriend does not give any percentage of his salary
to his parents. Same goes for his elder siblings. Their parents own
a small business so they provide very sufficiently for themselves.
They do not expect their daughter in laws to make kimchi, stay with
them after marriage or treat their daughter in laws as servants -
many of which are depicted in almost all Korean drama we
see.
But I guess every family is different :)
