2 divorced people, man has a child(?), and I remember a funny scene where the man thinks that the woman tries to kill herself in the sea, but was looking for something, the man jumps,tries to help her but he forgot that he couldn't swim so the woman saves him. DOES ANYONE KNOW THE NAME OF THIS DRAMA?

I think it's "One More Happy Ending "
at least the despription fits
Yessssss! Thank you!!!
You're Welcome ;)
