I'm still sad about the fact TVN cut this drama to 12 ep instead of 16 eps just because of low ratings. The drama is literally such a masterpiece. The cinematography gives so much comfort and warm feels to it, you can actually feel the warmness when you watch it.
Jung Haein's acting never disappoints and tbh this drama should rank one of his best ones out there. He adds so much emotion and expression to it. FL is also very good, I have loved her acting for a long time, and she was perfect for this role.

Storyline itself is written well. Although the start might not have that "hook" that usually most kdrama writers use in the first two episodes, you have to watch it very closely to actually understand the drama's progression. A lot of people think this drama's "technological" element let it down, but I think it's something very new.

Overall, I think this drama is just too perfect for masses to truly appreciate, so I'll be the only advocate for this lol
