Intriguing, smart, funny, sad, smart, sneaky. really good!
Acting is spot on, you really get love and hate characters, understanding their frustrastions and other feelings, totally hooked in and didn't really get boring at all as something new would appear and make you raise your eyebrows. Music fits perfectly with the emotions and scenes. Good story and up your street if you enjoyed watching "The Call" as they're similar concepts.
Although it was a hopeful open ending I still was a bit disappointed in it, also due to the fact that is just that season and no more once you've finished. I was really hoping to see the sweetest man Jae Han himself finally reunited with 0.5 but still worth it.
