It is amazing how these two young actors can display such a different level of emotions throughout the whole drama. Nam Ji Hyun and Do Kyung Soo's chemistry is undeniable and it is off the chart You can literally feel their love and longing for each other on the screen. Their acting was so natural and it was effortless and seamless. Nam ji hyun and Do Kyung soo were the excellent choices for Wondeok/Yool and Hong Shim/Yi Seoh and want to give full credit to casting director for bringing these two young amazing talented actors together to make this wonderful and yet heartwarming and funny drama. Wished it was longer than 16 episodes but liked how it ended leaving us to our imaginations (to write beautiful stories on our own). Main actors and supporting actors chemistries were amazing and they all complimented each other. 100 days my prince is truly one of the best drama of 2018, at least for me for it kept enticing and luring you with a storyline and off the chart chemistry among actors. Each actor brought life to each character they played to perfection. Truly loved this drama and can't seem to move away from this drama. Rewatched several times and discovered new things each time. Never get bored of WonShim bickering.... too cute. ... it is beyond words ...
