Can you tell me what taiwanese drama this is?

I think it' taiwanese, it could be korean but i don't know. So there's a rich boy and he bring's his soon to be wife onto a ship. Then there's this average girl that bring's her boyfriend onto the ship and pays for everything. She finds out he is using her eventually. But like accientally the rich boy and the average girl sleep together.. So I was wondering if you guys know what it's called. I found it on mysoju.com 2 years ago but i forgot what it was called?
