Overall I enjoyed this drama. The acting was excellent, the pacing and plot well done. My only cmplaint was that because they wanted to portray past events as unchangeable, the FL acts dumb in the past when she's trying to change it. She doesn't tell anyone around her what's going on. She doesn't speak up at the press conference, at the company, nor when she talks to the ML's dad on the phone. Just saying "I've got the proof!" would have changed the past. Heck even if she didn't before, she could have told his dad to meet her at the hospital to get the proof. Voila dad is saved, or just call an ambulance on the way to the park to meet him, or when he's dying on the ground perform cpr instead of leaving!!
