Backstory: Female lead name is Mu Xiao. She "got" into a car accident and forgotten her past, her lover. She is on a mission to find out that happen that caused her dad's death and car accident. She appears years after but now she goes by Su Yi.

The initially mysterious part is the identity of the female lead, whether she was Mu Xiao or not! ( spoiler r!!!!!!! She is)
She has lost all memories and tries to figure out the culprit behind it all. Male lead is the grandson to the Li family, He is currently the CEO. He loved Mu Xiao and has never forgotten about her. When the female lead Su Yi appears he is instantly attracted by her.
The female lead doesn't trust anyone ( not never the male lead). She tries to investigate on her own. Male lead eventually catches on and he tries to protect her. One of the biggest factor that is against the leads relationship is the grandfather !

Female lead thinks the grandfather is behind it all.

With the mystery also comes with some love! I here for the lovey parts, which was so sweet and fluffy ! Their relationship was so real and a lot of chemistry ! Things got hot haha... Like she trying to seduce him vice versa . Their love for each other was real!

However the process of solving for her fathers car accident was so slow! it was more on the back burner to me! Like there wasnt much solid development and unravelment of it. So towards the end it was kinda like....what happened? ....
