I thought we left these harmful tropes in 2005, but I guess not.

from the very beginning, the male lead stalks and pushes the female lead to do what he wants her to do. he is in a position of power, while she is her fathers caretaker and in debt and has literally no other options. not to mention that their personalities are basically caricatures- he's a violent loudmouth with a heart of gold, and she's a tsundere in a poor position that needs help- im not sure what they even like about each other besides their looks. (I mean, he became obsessed with her after seeing her once so). she has practically no lines, but we watch her expressions soften as she realizes he has a heart of gold, or whatever.
if I was her, id be terrified that someone else's debt was pushed on me, and even moreso when the debt collector stalks me and makes me hang out with him.
it was a cute love story I guess, if you ignore the reality women go through of being stalked and murdered by men. its time to stop portraying outdated tropes of "violent male leads with kind hearts using horrible tactics to coerce women into being with them" as "goals".

to make matters worse, when she has a chance at a new life she goes back to ML. even after his death, she has to be a caretaker AGAIN to his sick father. this girl cannot get a break.
