Sorry, but sibilings who are not blood related, but do grow up together, with a sister-brother mindset, should NOT fall in love with each other. It is very dirty to think about it and gives you incest vibes.
I stopped watching like in episode 6, simply because it was too depressing to watch, especially during a pandemic. However, it seems like it never stopped? No?
have you tried dramacool??? its free and has so many dramas of so many years. they upload episodes of all kinds…
Who said you need to watch it on Netflix? You can always watch it on Dramacool or something. They rip it of Netflix and let's be real, it's totally worth it since Netflix is a pedophile company anyways.
