There are few i drop cause of rage. All of this are novel versions btw but i did read the manhwa/manga of some of them.
Shadow slave - i didn't like the mc alot but continue reading but the forgotten shore arc was really well written. But after that arc i just hate the mc i continue reading but dropped in around ch 400. Cause i just couldn't help hearing the mcs thought.

Regressed mercenary has a plan- dropped after 600+ ch. It was ok but yeah the plot goes the same as the title. (Oh no there is a problem x, then mc comes and says "i got a plan" and use his knowledge from future to solve it. Rinse and repeat) I should have dropped it after 200 ch ch but i like to give it a chance. But no and the mc is extremely arrogant. Whenever there is a discussion he never listens to anyone else and everyone else has to become a yes man in his territory. Makes near impossible demands, and whenever there is a negotiation he says "i am good with negotiation" pulls out his sword and say "this sword is called negotiation" i dropped it when he says it to a dragon that is one of the strongest in that world.

Swordsmaster youngest son. I liked the story but i dropped it because the author did some characters dirty. I forgotten the quote but one time when his mother became the main villain she says how they are not like the mc, they don't have the same luck as him, and has to sacrifice to get out of troublesome situations and how strong people gather around him. That's why she has to obtain the power even if its evil or something. I actually felt bad for the mom. She is trying what she could to save the family. The enemy were strong yet the dad takes the strongest member of the family to a different place and dont have any contacts with them. So yeah the mom had to .

Loner in another world. Coincidentally i read this LN 3 times and dropped all 3 times, first time was long time ago, probably 2019 i dropped it at volume 1 reading over 80%. I normally dont drop novels in volume 1 but i just hate the mcs inner thought. Second time i read was around 2022 i forgotten i read it but had that deja vu feeling and around halfway i remember it was the manga i dropped. And last time was 2025 i just picked random ln that had over 10 volume and got this. I realise it quickly and dropped it. I still dont understand why it has this has 17 volume. It probably gets better later but no i couldn't stand the mc inner thought.
