I love how this is a female-based drama, Hyeon actually ended up being my most favorite character. The cast did well in their roles, but to be honest, I have gotten bored at some parts due to feeling like the story was super dragged on and mostly skimmed. The romantic relationships in this show seem very convoluted and appear more complicated than they should be. There are some minor flaws here and there. But, I do admit that this is one of the best dramas centering around technology. I would recommend everyone to watch this drama over Start-Up.
