First of all, I really enjoyed the plot. It's not an ordinary one. In fact, I love how it treats about high technology and the way it effects society. Something that surprised me actually is that this kdrama portrayed homosexuality! South Korea is a pretty conservative country and the fact that the director had insisted on portraying it makes me realize their society is becoming more accepting :)
The feeling of anxiety, always being on the lookout, embarrassment, acceptance, denial, excitement were well portrayed by the main leads. I support Kim So hyun haha, she's a very good actress. I've known her since School 2015 and I know her capability. Our rookies here Jung Ga Ram and Song Kang did an excellent job and I'm sure they'll be very successful in their acting career in the future.
Okay now the things i disliked about the character: Sun Oh.
He's very possessive, clingy, creepy and hard to like. I couldn't really stand his character. The moment he went after Jojo, I lost it. Is something wrong with him? He clearly knows that Hyeyeong, his loyal and kind childhood friend liked her and he STILL WENT AFTER HER. It was almost as if he didn't want Hyeyeong to get the girl and started to used his'' charms'' that any girl can fall for to Jojo for which she in fact did fall for. It's so disgusting to the part where Song kang says something like'' Oh you were never by my side all along''. Like *****, first of all, he did let you have the girl and didnt complain about it. Grow up.
Anyways yeah that was my rant about how unbelievably disgusting his character is.
Overally, good show that is binge worthy. We'll see what happens!
