Hello ! I'm quite bored lately and I feel like there's nothing interesting out there to watch , so recommend some super addictive dramas that will make me go on a marathon ! I miss the feeling when I first discovered korean dramas ...that being said, I want something to watch that will even make me go crazy over.

thank you for reading y'all ;))

Nine time travels is what you are looking for. A heart attack with every episode if you know what i mean!
I've noticed there is no Love me if you dare on your list. It was pretty addictive to me.
The King's Woman (Cdrama)....you can only binge up to ep 16 or so...because its currently airing.  It amazing. 
missing noir 
love me if you dare
queen of ambition 
I saw you have Heart to Heart to your PTW list. I loved that romcom. It's good. 
Kleun Cheewit (thai drama) is super addictive! I was glued to my screen and didn't watch anything else till I finished it 

But if you'd prefer something Korean,
I'd second Signal
Tunnel, is also a good one to binge-watch
Circle

If you'd like rom-com
