I don't have any interest anymore I didn't even read the last 2 chapters should I drop it?

Yes you should, queen

You can do whatever you want! But I honestly feel ,like the story is going downhill with each chapter upload. Things are getting boring and there has been too much repetition in how the characters act, doubling down on one to make the other shittier. I you like reading that type of story, this one is for you, but if you like something with a better story, I would suggest moving onto something else
This story just adds toxicity to keep readers busy and no excellent writing like other manhwa with heavy topics.
