First of all, I made an account at mydramalist.com only because I can't help but to really want to review this drama. I can't give a perfect score only because there's no perfect score, or not yet at least. Now, the last time I made a list of drama I watched for both Japanese, Taiwanese and Korean, each have sum up to at least 50. So yes, I have enough credibility :P Here are my reasonings and I'm doing it in points so to make it easier to read. The reason why i love it: 1. Its original - the concept with the 90s and the friendship is fresh! 2. Awesome acting 3. The story is not relying on 'famous' people. They ARE idols, but not top idols to the point that they can act badly and people will still watch. 4. There's good chemistry. 5. Its funny. 6. Almost for the longest time, I can FINALLY unable to predict the end of the story. The tiny bit that I don't like: (SPOILER ALERT) 1. Why do they have to sleep before getting married. Not that it's bad. But so unoriginal in that part. I mean the story and the friendship is so cute and pure, why not making it different just for once. Haven't seen that for the longest time. I truly recommend this drama! Love it!
