A bit underrated now though I do know it's getting more traction these days—No More Eurydice by Baek Daekal is crazy angsty and just well-written overall that I'd recommend... Would also rec Love or Hate by Yeongha, and Curveball and Splitter by Bad Pharmacy (both are more on the drama+angst side and very character-heavy)!
Also extremely unemployed, here u go !
