They Casted the perfect actors for this (talking about the Main Roles and some of the Supporting Roles, You will know it if you Watched it till the End) they have this chemistry between them that fits each other.
Even though it was 40 EP you will feel like its not enough once you reach EP 30 Onwards (Stated from the Headline Above)

Downside is you might find this show boring because it has a slow progression but bear with it, YOU will find yourself smiling
at the end, Also when they use Greenscreen for the Car Scenes (some of it) its kinda off hahhahaha

All in all it is a GOOD Watch and has a good Rewatch Value also S2 is really needed hahahhah!
