According to previous tl's website there were copyright issues so they had to stop. Previously it was officially licensed on smackjieves but that's also been removed. Now it's been licensed on Webtoon French though. ( https://www.webtoons.com/fr/romance/unlucky-mansion/list?title_no=2121)
I've seen authors removing the licensing from one platform to move to another in the past so that could be what's happening to English ver. as well. (๑•ㅂ•)و✧
Can someone PLEASE pick this up??? Or if not, can anyone tell me where I can read the completed version for FREE T_T
