It should be where it says publisher in NU page. just copy the KR title and paste in search bar of publisher site. KR novels aren't like CN novels that have multiple pirate sites. Also, I believe Top Management has been cancelled/on hiatus in KR.
On hiatus, check munpia, but there's the vip wall, like usual Btw, munpia is the korean version of qidian, just so you know
I'm so stupid , I was looking at the left column under the art for the Korean Name while it was at the centre of the page. Thanks.
