I think it was a taiwanese drama about twins that were separated and one went with the mom and one went with the dad. One of them works (more athletic) in a fish show with the father and the other one is sickly and with the mom (i think), who owns a hotel. Then the sick one leaves to get treatment and the healthy one returns. The healthy one pretends to be the sick one for a while and wins a contest for the family.
There is also fighting between 2 hotels, where the main girl works (who loses a lot of weight and is clumsy.. i think she burns the house down at one point??).
Anyways, does anyone know the title for this one. Sorry if it's not in the right section .....
