can you bpl give me name  of drama like my husband oh jak doo 

romance / comedy/ drama 

Haeundae Lovers is kind of like Oh Jak Doo with reverse genders + amnesia, lol.  (Also has Kim Kang Woo, so it might be why I thought of it.  Otherwise, they're not much alike other than both being generally in the same genre.)

What exactly is it that you like about My Husband Oh Jak Doo that you'd like to find in another drama?  You might get better responses if you're more specific.
