I don’t get the rave

I liked the cast for the most part. But the hacker, although I liked his acting and ability to be humourous, I hate his hacking acting, it honestly really lowered my rating. And although this drama is shorter than the usual 16 episode, the story felt like it was too dragged on. I almost dropped it. I liked Ah-ryeong’s character but I wish she was given more action scenes or just more scenes to showcase her tricks/skills besides Hari. Like his character overshadowed everyone else. His acting was good.
