9/10 is my rating. This is a 2018 historical romance with 16 (+2) 67-85 minute episodes. Alternate titles are 100 Days My Husband and The 100 Day Husband.

As the nephew of the king, Lee Yul (Do Kyung-soo) is told to keep a low profile and not do anything, such as excel in learning, that would make the king feel threatened. So, instead of studying he spends his days playing and unintentionally bullies the other kids. When Yoon Yi-seo/Yeon Hong-shim (Nam Ji-Hyun) notices Yul’s behavior, as a fellow noble, she scolds Yul for using his authority to make the other children do as he wishes. Yi-seo also teases Yul for his lack of knowledge. Yul has an immediate crush on the pretty and spunky Yi-seo and starts studying to impress her. Before the children can become closer friends, Yul’s ambitious father participates in overthrowing the royal family and killing them and all their supporters, including Yi-seo’s father who was a right hand man of the king. The intent was to kill the entire family but Yi-seo’s brother helps her escape. is the King's nephew who enjoys spending his days playing instead of studying.

10 years later Yul is a cold, distant crown Prince who is reluctantly married to Crown Princess, Kim So-hye (Han So-hee). The marriage was a condition of Vice-premier Kim Cha-eon (Jo Sung-ha) who carried out the overthrow of the former king which allowed Yul’s father to ascend to the throne. There is a lot of pressure on Yul to consummate the marriage with the Crown Princess and the current claim is he must to end the drought. His response is all unmarried people in the kingdom should become married instead. The punishment for not following the royal decree is flogging. Before Hong-shim can be punished for resisting marriage, an assassination attempt leaves Yul with memory loss and he is saved by Hong-shim’s adoptive father. To keep aging-shim from being flogged, her adoptive father hides Yul’s identity and tells the two they are affianced. Will this pretend relationship become real love?

*spoiler alert. I really liked the premise that he loses his memory and lives as a commoner. I like the backstory with the evil left chancellor and the fact that Hong-shim was also nobility that had to live as a peasant. I liked how his character develop from a cold noble to a person that wanted to be a contributor. I thought their relationship was really cute and believable and I loved her adopted father. The timing of when he discovered who he really was worked well. The only part that I found a bit disappointing was toward the end when Yi-sei was like we can’t be together because of what my brother did. I did not think that was a good reason for them not to be together and I felt like she was more using it as an excuse because she was intimidated by the fact that he was the crown prince. To me it made it as if she dId not love him enough to overcome that which conflicted with the relationship they had as commoners in the village. I also thought he should’ve insisted they be together more and reassured her when she was stubbornly insisting they would not work because of past events. I wished Yi-seo’s brother would have lived and fought with the prince to redeem himself. What he did was wrong but I did not feel there was any way he could’ve helped it. I was really happy that the king did not kill the crown princess. That was consistent with his character. The part where they finally got back together felt rushed after all they had overcome to be able to be together. I would’ve liked to have seen them together and maybe the wedding with the king there. Despite the small drawbacks it is overall a very entertaining and heartwarming story. I highly recommend it for romance, light humor, and historical components.
