Firstly, the story is though predictable but addicting to binge.
It is cute but with a sensible plot for a Kdrama.
The ending is satisfactory. I just wish there was more to it.

The acting is good.
Just that the fight scenes seem fake.

But for a web series, the CGI was good enough.
The music is memorable and suits the scenes.

For a rewatch, it is worth if you just wanna see their moments together. Bonus, I really liked how they handled the girl shaming scene.
