this drama is so so good- i watched it in one sitting. 22:00 to 1:16- i watched it all. this bl is so good, it has the perfect balance of romance and plot- it correctly uses the plot to build the couples relationship and gives the perfect fluff to plot ratio. the main couple’s chemistry is AMAZING- and their relationship dynamic is to die for. they’re so adorable together and the way that this drama allows the mc to come out of his shell and begin to feel real emotion is so amazing. i also love how at the beginning he compares his feelings to the functions of a computer but at the end he abandons the analogy and accepts his feelings as they are- i love the small details of development. this director needs a raise because this plot was beautifully written and executed. every detail was perfect. i love this drama sm and the acting was amazing. best bl i’ve watched ever. watch it !!
