This was my favorite version of the F4 series. I've watched the same plot many times in Japanese, Korean and Chinese. Thailand's version of F4 does not disappoint initially. It follows Boys Over Flowers in that there IS a love triangle. What F4 Thailand does better is that
1) Our ML isn't that toxic
2) Our FL isn't that annoying
3) They introduce the FL's controlling mother early on and establishes her as a villain from the very beginning.
The first half of this show is truly adorable and you definitely root for the ML a lot more than in the other versions.

Where this show goes downhill is in the 2nd half where it is simply... too draggy. I ended up skipping majority of the show towards the end because we no longer see much Thyme x Gorya. Also, while Thyme/Gorya are my favourite couple from all the versions, the second couple isn't. Kim Beom & Kim So Eun were truly the GOATs.

The ending was... stupid. She somehow managed to convince Thyme's mother in NO TIME to be less hard-hearted and let Thyme do what he wants. Wow.

You'll definitely get butterflies initially (also Thyme/Ren are so cute) but it does go downhill later. Would've been an 8, but the later episodes were too unsatisfactory.
