Other than the great casting, the show itself is just, muah, chef's kiss.

The emotions that are portrayed feel so real and is conveyed very well by the actors.

Other than that, it doesnt feel corny or copied like other shows can feel, it instead feels very unique and original (I know it's based on a webtoon, but ykwim)

Moreover the open ending left off so well to introduce season 2 even though I'm sad that Choi hyun wook will be in that season. I look forward to seeing more of this show and it's definetely a great and thrilling watch!

I recommend strongly, on my mother, it's amazing!
