wait there& #39;s a k-drama i need help identifying.

something about a beach/resort. at the end there is a marriage between the girl& #39;s mom and someone else. the main lead lost his mom but she ended up having a restaurant on the beach.

wait i remember they slept together in his car on the beach, when he woke up he was naked and the ahjummas are laughing at him.

figured it out, t& #39;was my secret romance
