Her remaining a gumiho completely goes against all the logic the series built for the most of the time. After all, Eun-ho's trauma and her fear of becoming human come exactly from watching her eonnie suffer through her mortal life, grow old, and pass away, leaving her all alone. The ending, where she remains a gumiho and faces the exact same scenario with mortal Si-yeol, is totally illogical and straight down cruel to the main character. He will grow old and die, while she will keep living. Instead of learning from Geum-ho's story and give her some form of character development, the creators threw them into a loop of suffering and called it a 'happy ending'.
in the 2nd timeline when they were in the present it was still the same even when they were in their own bodies,…
I mean she starts to take more into her own hands in the last episode, and as for before his first death se was diagnosed with some mental problem which made her not able to feel emotions properly, which explains why she would be more responsive than pro acting (I wonder where that disorder went later but I guess kdrama logic and u Jae’s death unblocked it for her). I’m not making excuses for her and I too wish she would take more initiative, but to me her behavior makes sense in a way. I just hope she will continue to take initiative in later episodes like she did in ep 6
The male and female twins body swapping is controversial
It’s not a BL in the same way that my girlfriend is a man is not a BL to me, but still of seeing 2 men being flirty makes it controversial I have no words
The male and female twins body swapping is controversial
it’s so sad honestly. I do not personally consider it BL since ML is clearly in love with HaNa, and even inside HaRu the person he likes is still HaNa. Although I do think ML is bi since he finds HaNa attractive even in HaRu’s body
I’m curious what would happen if Nam si yeon did not enter the plane after being warned. Would the time loop…
Also in og timeline Jun hee and Si yeon met even without time travel and she is later revealed to had developed a crush on this “oppa who was nice to her when she was 11”. I wonder if that happened too in the reset timeline.
I’m curious what would happen if Nam si yeon did not enter the plane after being warned. Would the time loop collapse as well? Or maby he would die anyway in the next flight? Or maby something completely different…
