If you guys like this story then I recommend Cheonsaeng Yeonbun which has a similar plot, I haven't read that one in a long time but I'm pretty sure it was pretty good
omg I remember that being so good too. Like I was touched even though I barely remember any of it I saw the cover when I clicked your link and yes people should go read it IDK why, but the feeling I still have is amazing
