I'm not sure if anyone remembers this fanfic adaptation. It's daragon and the story talks about jiyong who hates his new stepmother played by sandara. Sandara cares for him and his daughter, but jiyong hates her because she married his dad and she's younger than him. Jiyong is married to kiko and they have one daughter.

So in the story, the kwon family is on a vacation and jiyong hates every second of it because of sandara and his daughter is really fond of her. He says really hurtful things to her. Then, during a game of spin the bottle, they kissed and suddenly jiyong remembers that he met sandara in a beach 10 or 7 years ago, fell in love with her after saving her from drowning but he gets into an accident and had Amnesia. 

Now, he remembers her, he rembers his feeling for her and wants them to have an affair. He also regrets every mean thing he said and did to her. He also hates his father more now because of this. 

Sandara is an aspiring writer in this story.

Hope someone can tell me the title of this fix and if possible also the link. 

Thanks.
