I liked Key's character. He was simple and cute. Everyone else was awkward. Chen tried to be romantic but it turns out to be a cringe. Libby's crying was also cringy. Martin was just there. There's also 2 eye candy men. I guess it wasn't so bad for new actors.
OST wasn't rememberable.
Simple short story. It was the acting that kept bothering me because it just felt unnatural.
You're not going to get much out of this series. I was expecting a lot from this series according to the positive reviews, but it just felt bland to me.
