DISCLAIMER: I have only seen Boys Over Flowers once, which was about 8 years ago. I got so frustrated with the amnesia and everything else that I skipped to the end. Therefore, I think I went into this drama with a mostly open mind, since I've heard that the Taiwanese version was better than Korea's.

When I started watching this drama, I had no idea what a roller coaster ride I was in for. It made me cry. Dramas NEVER make me cry-- not even the melodramas or the tragedies. I was a mess when the leads were in London on their date (hopefully that doesn't spoil too much) and they were crying. I lost it.
Yes the drama is extremely unrealistic, but isn't the point of entertainment to take us away from reality? I guess people want to be taken to different places in their fantasies.
What's not to love about this drama? It's so feel-good. It left me with so many warm fuzzies. F4 has awesome chemistry together and yes they are all tall, handsome guys. Darren Chen and Dylan Wang I felt particularly nailed their roles. Darren Chen's Huaze Lei made me flashback to when I watched Boys Over Flowers. Also, he's adorable.
Dylan Wang... wow. I was blown away by his performance. Playing a character like Dao Ming Si would be difficult, especially showing the slow character development he goes through. Dylan Wang made the 180 switch of bad boy-turned-good Dao Ming Si completely believable. He and Shen Yue have AMAZING chemistry. When they were together, it felt like they weren't even acting at all.

I also loved how there weren't annoying misunderstandings keeping the couple apart. They were kept apart by outside forces, which was still frustrating but much less so.

Overall, the acting, writing, everything is just amazingly well done. I will definitely be rewatching this drama multiple times. This drama made me believe in love again.
