10/10 is my rating. This is a 2020 South Korean Romantic Drama with 16, 72-85 minute episodes.


As young children, Seo Dal-mi (Bae Suzy) and her sister became separated when their mother and father divorced. Seo-Dal-mi chose to stay with her father in South Korea and her sister went with their mother who remarried. Dal-mi's step-father is a wealthy businessman who was able to provide Dal-mi's mother and sister with wealth and status. Dal-mi's father died on the brink of receiving an investment to realize his dream of the next big thing in the tech industry. Wanting to fulfill her father's dream and show her mom and sister that she made the right choice in staying with her father, Dal-mi strives to make a big splash on the tech scene as the CEO to a start-up. Dreams for a successful start-up business start and sometimes finish with admittance to the start-up groomer, Sandbox, which is South Korea's version of Silicon Valley. Nam Do-san (Nam joo-hyuk) was a "math genius" as a young boy and grew up to be a genius coder. He founded a start-up, Samsan Tech, with two close friends. With his business struggling, Do-san agrees to play the role of stand-in as Dal-mi's first love who she "met" as a pen pal when she needs a date to an important event. The young dreamers apply to Sandbox and all are accepted. The situation becomes complicated when Dal-mi's actual pen pal also comes into her life and discovers he has feelings for her. Will these young dreamers realize their dreams and overcome nearly impossible odds to form a successful start-up. Who will Dal-mi end up with, the man who wrote her letters and supported her in her time of greatest need, or this "new" love that is the perfect partner for her aspirations?


Spoilers* At the start we are introduced to Dal-mi's father and it was a sad moment when he died after just realizing his dream of getting investors to start a business. Young Dal-mi had elected to stay with her father when her mother and father divorced. The relationship between the Dal-mi and her father was very heartwarming. Her father's mother, the grandmother, was also a very compelling character and it was understandable why so many people were drawn to her. I love how the grandmother adopted this orphaned young man in spirit and took care of him despite his bristly exterior. The grandmother also took such careful care of Dal-mi not just physically but emotionally after her father died. It was an interesting slice of life to see what a technology based start up might go through trying to get their idea(s) off the ground. The friendships, romances, and just the character development was all very well done and interesting. I really liked 2nd guy but I did not feel too bad for him to lose the girl as it had taken him too much time to realize he liked her and, even then, he was too slow to show her how he felt. I also liked him to the extent that I was glad she didn't wind up with him because she would never have loved him as much as he loved her. The 2nd guy could have been unkind and kept Do-san and Dal-mi apart by withholding information but he cared enough about both that he told them despite it being against his interest to do so. I liked Nam Joo-hyuk in "Weightlifting Fairy Kim Bok-joo" and "The Bride of Haeback" he is a very diverse and talented actor. Suzy Bae is just incredible. I first saw her in "While You Were Sleeping" and loved the role she played as a very vulnerable person troubled by visions she could not control. There was so much chemistry between the two leads and they looked very good together. It definitely made me root for their relationship. It was interesting to observe how each team member brought talent to the table and how they moved so many concepts into developed ideas into reality. I highly recommend this and would readily watch it again in the future. One of my new favorites.
