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

Just gives off the same vibes. Melancholic, slow, soft, healing with a dash of crazy traumatic background

Both agency and misaeng have a rookie vs the mean boss that turn into each others greatest supporters

Both have the different "faces" different "actors" playing one character
Tho from the names one is romcom and another is death?

Both the glory and why her have the same vibe. FL going against a big enemy. And also both have a mismatched age gap imo

Both fls are one of my favorites. Both rock a bob and more seriously, both dramas are about 2 competent, smart, beautiful women that builded their careers from the ground up but both face the same discrimination and close mindedness of the man centered corruptions
Both also have 2 psycho bosses that do know and acknowledge the fls powers but still can't tolerate a woman in power

The business stepup, girlboss, and corporate struggles are the same in both dramas
Tho agency sadly lacks the female centredness tho I do hope 2fl is going to build a bond and support fl
