Amantes de Haeundae (2012)

Both feature an amnesiac, people who start out as/should be enemies (who later fall in love) and some truly laugh out loud moments!

In Haeundae Lovers a prosecutor loses his memories only to fall in love with a former thugs daughter. And in the case of Fantasy Couple a rich (but spoiled) lady falls of her yacht only to be found in the hospital by a guy who wants to extract revenge on her.

The plot and general feel of these dramas are very similar and if you liked one of them you'll be sure to like the other. Enjoy!

It's also about a Men going undercover. Then through a accident, he also lose his memories and thinks he is one of the gangsters.

They both feature a male lead who loses his memory and ends up living with the female lead.

There's a similar theme of former gangsters attempting to run a legitimate business and leave their life of crime. Both dramas have kind of a found family situation going one.

Both 'Haeundae Lovers (2012)' and 'Woman of 9.9 Billion (2019)' feature Kim Kang Woo and Cho Yeo Jung as the main leads.

Same adorable lead actress, Both are fun romantic comedies with lead males that despite having a complicated and rocky relationship start with the spunky lead actress they fall for her. There is an interesting dynamic in both that put the actress in a position of power over the male leads early on. There is also a time in each that the lead male seems a bit emotionally dependent on the leading lady. the main difference is that HL deals with gangsters and DIL deals with bad marriages.

The main character loses his memory and falls in love with the main girl but he has to return to his real life and love interest. Who will he choose?

The storyline look same..Haeundae Lovers is about a prosecutor who goes undercover to infiltrate a crime family in Haeundae, Busan, then gets into an accident and loses his memory. Thinking he's a gangster, he falls in love with the mob boss's daughter.
