They say a picture is worth a thousand words...

Well, I am not sure how accurate that formula is when it comes to manga, but I was able to get the gist (I think) of the remaining Her Pet chapters (up to the final chapter 72) by looking at the pictures in the free (legal) original versions (and, by necessity, ignoring the words in Korean).

Assuming you have a (free) account on http://www.lezhin.com/en (if not, you need to sign up first), you can find all the chapters at

By the way, I really enjoyed this series until Chapter 55, but was disappointed by almost everything that happened afterwards... :-(
