if anyone is interested in reading the novel, here's the link, but it does seem like it's machine translated tho.

the author themselves is a medical professional so it does have a good chunk of medical jargon and it's a realistic one too. they did change a bit of the character profile and setting and expanded a bit on other characters in the drama. the novel is told more from the fl's pov. the extra tho was what kills me and made me cry the whole night.

gonna read the extra after this drama ends coz i like to hurt myself

thanks
