I also dropped Back from the Brink (what a coincidence) at episode 5. Beside what happened on episode 1, I no longer remember the plot.
I completed https://kisskh.at/28744-likhit-haeng-jan. It's really fun and the plot is interesting. Only the episode length a bit disturbing (1 hour 30 minutes to 1 hour 40 minutes times 14 episodes). The first Thai historical drama I completed. To be exact it's a time travel drama where two women with the same face but different personalities from two different era switched places through a painting. The woman from modern era (Opal) was a police, brave and straightforward. The woman from the past (Duengkaw) was an aristocrat daughter, sweet and timid. MLs were a palace doctor and a police. And it has happy ending.
I'm also still watching The East Palace episode 4 and Gochisousan episode 29 (though I'm unable to find episode 9 and episode 25, if someone happened to see one, please share the links). And today https://kisskh.at/692399-the-mystic-nine-2 with William Chan and Zeng Shun Xi premieres. Can't wait!
