I love short and easy to watch dramas, I loved Page Turner, Addicted, Click Your Heart, To Be Continued and I love this. Okay, I'm aware of it's flaws but honestly, if you want something easy to watch that doesn't require all your brain power, this is it. The Good: The way the instant messages and animations are done is amazing. It is really refreshing to be able to see the texts on screen in a way that doesn't mean showing the phone screen over someones shoulder. The two mains manage to have good chemistry without even meeting, which is impressive. Kim Jiwon's character is amazing too, she does the rich family's daughter act really well. The Bad: The ending is the one of the two things that put a dampener on it for me. It didn't feel complete. We saw the four years later shot but it still didn't feel well rounded. If they could add a third episode with the conclusion of the story then it'd be a 10/10 drama. I'm not really sure where I stand with the morals of this story either. I mean both people are cheating on their significant others and we're just supposed to be fine with it? Conclusion: Watch it if you've got a spare two hours! It's definitely worth it. Just be careful if you don't like incomplete endings.
