I'll start with the positives because there are a few. The acting and the cast were great. They all portrayed their characters really well. The characters were believable because the acting was so good. The music was also good. In all fairness, the story was good to start with and that's why I continued watching. The story becomes horrific after a plot twist and I urge you not to watch this if you're looking for something cute and lighthearted. I wouldn't watch it again.

So, what's wrong with the story?
The romance.

The romance between the two leads starts off fine and despite breakups, they end up together. Unfortunately, you start wishing they hadn't. You start wishing that she got the hell out of there. The male lead is creepy, obsessive, and stalkerish. He's liked her for years and altered her medical records just to make her notice him. There are other ways to get someone to notice you, you don't have to invade their privacy. Tracking devices, gaslighting, lies, and manipulation. He was toxic and showed abusive behavior. Maybe I could've enjoyed it more if she didn't run back to him. Honestly, I think it sets a bad example for younger viewers. The toxic relationship is twisted into something 'romantic' and 'sweet'. He isn't caring, he's obsessive. People can change but the female lead didn't give him enough time to prove he had changed.

I don't recommend this at all. I really hope that if you watch this you can see the toxicity. His actions were not sweet and I'm disappointed that they are sometimes viewed as sweet.
