I don't know how i even finished this series, when now, i will literally drop a show INSTANTLY if i am not vibing with it. If i think back to the storyline, it seems pretty good on paper. He needs to pay back the "debt" that was left behind by his father and she's the collector, i just think it may have not been executed that good. Or maybe it's just not my taste. I loved the cast and some of the ost, but i found myself waiting for it to be over. Idk maybe i just didn't really click with the story and tbh i barely remember it, even now. I really wished that i had liked it more, but i hope IU does more acting.
