In DA it is two Lady's from the past who have lost thier husband's to death travel to the future where they meet men who look just like thier husbands. THis series has mostly drama and romance. It's a bit darker and aimed at a more mature audience than QIHM.

I thought the chemistry between lead actors was better in BMF,
I did like 609 Bedtime Story but it did have some confusing parts in it,

it has a similiar feel. There is humour drama and a mystery to be solved. Although both stories are toatlly different.m PN is about a girl that travels into the past, SM is about a half Thia half Spanish girl that speaks English and doesn't fit it. Both have good endings although PN does has some sadness in it.
