'A Piece of your Mind' Episode 1: Jung Hae-in and Chae So-bin bring forth a complex tale about unrequited love
'A Piece of your Mind' introduces Jung Hae-in as Moon Ha Won, an AI developer who loves classical music. He develops an AI technology that would see an individual's characteristics reflect in the AI. He uses himself to work out the technology but what he cannot figure out is the "point of reaction". Figuring this out is of utmost importance because this is what will instill the individual character traits in the AI.
Then we have Chae Seo-bin as Han Seo Woo. She plays a music engineer. The studio where she records music is now being shut down because the landlord wants to sell the building. Ha Won hears the last piece of music to ever be recorded in this studio as he passes by the building and when he opens the door, he has flashes from his childhood -- of practicing to play the piano with a girl. The music engineer in the studio is surprised to see him but tells him that he is lucky because he is now hearing this piece of music. Their fates are now intertwined in ways that we can only guess for now.
As of now, though, all the attention is on Ha Won and his AI on the show. When he is about to leave the studio though, the AI responds to the piece of music by humming along to the piece and this leads to a pause in Ha Won's thoughts filled with the past. This occurs exactly when lightning struck on a dark, cloudy day and Ha Won has successfully found what he had been searching for to make his AI adapt his characteristics. Turns out, his past includes a girl, Kim Ji-soo (Park Joo Hyun) whom he fell in love with when he was young and lived in Oslo. She is the same girl who had appeared in the flashes before as well and it is his memories with her that unlocks what he needs to get his AI working.
Ha Won also decided that he wants a recording of Ji-soo now as a keepsake. He feels that a recording of her would be like a piece of her that he could have with him even if he cannot be with her. Now that Ha Won also bought the studio, he decides to use Seo-woo to get the recording. Ji-soo seems to be struggling with depression and Seo Woo who has made her acquaintance tries to help her overcome it a little bit and also helps Ha-Won in the process by recording her voice.
While Seo Woo has met both Ha Won and Ji-soo, she doesn't realize that the former is, in fact, Ha Won or that the latter happens to be this man's, first love. In one of the scenes, she asks the man whom she refers to as "Before Dawn" if she should let the two moonstruck lovers meet. It is ironic that she would address this to him, but this scene also shows us where Ha Won's mind is.
The first episode introduces us to three interesting characters and they get involved in a complicated game of hide and seek. By the end of the episode, what one anticipates the most is what would happen when the game ends. How would their fates keep their relationships intact?
New episodes of 'A Piece of Mind', or also known as 'Half of a Half' will drop on tvN on Mondays and Tuesdays at 9 pm KST.
