Hey I happened to find an article about this drama. Honestly I didn't really understand it but for people interested in... I guess psychology? And maybe relationship theory if that's a thing? Well then this is for you. It's about something called Tie Up Theory. 

Essentially I guess it's about how kdramas are a unique way of exploring the nuances behind attraction?

I was surprised it's an NIH article. Who would've thought!!! Reading it now. Thank you.

Enjoy! ^_^
