First of all, I am one of the biggest fan of SWDBS. It is still my number 1 favourite kdrama. When they decided to make a spin off for the series, I already had a bad feeling.
But I just give it a chance and as expected, it is terrible.

It is super terrible if it is not spin off. It's name doesn't stand a chance to be next to SWDBS.

The plot is everywhere. Not only that, I think the 3 main lead (ML, FL and the villain) are so green that make this series more unwatchable. The FL is not suitable for this kind of character. She is good in squid game and AOUAD, but this one, she is the weakest link. She got no chemistry with both of the men since she act like a kid. Why does she need to be act cute like this? The ML got no charisma. Hence, he looks like a side character. Fyi, In Gukdoo in SWDBS is more interesting to watch even though he got limited screentime in there. And the villain is not convincing enough to be a villain. The bad guy in SWDBS was more scary than this one. See....I can't avoid to keep comparing it with SWDBS because it is the same writer and supposedly it has the same vibe.

So let me summarize, this series is not a romcom because it has no romance and no comedy. It is not a thriller because I don't feel thrilled at all. That's all...
