If you're ever wondering about what chapters are released, you can check on lezhin here https://www.lezhin.com/en/comic/killingstalking
The English and Korean chapters release on the same day.
Currently KS is on hiatus until July https://twitter.com/kooo_gi/status/872780550330761216/photo/1
English lezhin updates are simultaneous with the raws
or you can search them up on instagram.
Some killing stalking fan accounts link to other accounts that release the new chapters as soon as they are released on Lezhin ( all in instagram ).
I was wondering if there is a Raw update for this yet because I really want to know what Sanwoo is going to do.
