Both dramas are a bit “supernatural”, and in a way both drama leads “trust” and “believe” the other lead because of their power
Both have that “mystery stalker” threat that the whole town worries about
Plus both have the cop second lead

Both dramas have a similar plot move, related to partying and drugs
Tho one is about a drug dealer teen and another is about an influencer walking between the lines of the rich and the Mormons

Both have the same high quality production, each shot feels like a painting
Both have the “poor world mix with rich world”, the mystery, murder and female centered makjang

Korean demon plots are a handful, sometimes they’re good sometimes they’re silly
But I feel the same vibes from these two
The dynamic between the 2 leads, not being cops or demon slayers, they’re normal but one knows a lot of information

Both are about women that put their lives on hold and lived as the perfect housewife thinking that’s the source of happiness
Both get a wake up call when they discover the husband they worshipped so much is cheating on them
And instead of crying about it both go back to their dreams and make their own happiness

Both FL in doctor cha and 2FL in Spring turns to Spring share the same plotline
Both of them are slaves to their housewife persona while their husbands mistreat and cheats on them
Both are also clueless on the matter and put a smile having been taught everything will be ok as long as the husband is happy…

Both also share the same “daughter”
Tho one is a body switch fantasy and the other is just a wake up call switch

Both oasis 1ml and save me 2ml were wrongfully accused and put to jail
Both also have angsty friendships with the other mls. They were both close and betrayed by their friends and social status

Granted both have different set ups but both also fight against an unjust system and ruler

they're both on the same time period, the aesthetics and angst are similar, the plot story are naturally different as there are no 100% similar dramas
But the story of 80s/90s youth fighting for their rights and beliefs are similar

Both oasis and youth of may follow the same time period. The struggles, the political movement and the angst

Both are from the same time period. The struggles of the political world and the youth dragged into it

The trio meeting scene had the same vibe. 2 friends falling for one girl, then running away together from hooligans and the betrayal of friendship
Now for me in my country sunho was right while hwi was wrong. But here it's obviously the other way around

Both have the seemingly cold female character and the neglected kid
Both female leads turn out to be caring and they build a "motherly/aunty" bond with the kid who adores and looks up to them
