Madk ending gives same vibes as killing stalking ending in a way in my opinion.
my man, thanks for the suggestions I read the first one, imma go cry some now, peace (=・ω・=)
I have been struggling, to find a good old manhwa that is actually worth my time. Honestly, everything's just so cliché and repetitive, the characters aren't compelling and just it's blech. One of the manhwas that I enjoyed so much was Killing Stalking. I found everything about it to be so new and different and just a breath of fresh air. I don't care what the genre is I just want it to be worth it. Thank you.
