This is actually completed already. Have not checked if there will be side stories. . . But I really love the art and thought there will be like a chasing or redemption arc, there was none. Or it felt like it did not happen (I posted before that MC finally left the mansion and I thought there will be a long ass chasing arc but i only got disappointed). The ending felt rush, like the author just want to complete it already. I used to really look forward on every chapters of this but it usually gets delayed and now the ending. Plus another thing that got me disappointment with the ending was there was a change with the art. Like it's already the last chapter, why did it have to happen :') not a major change but few scenes.
I'd still read the english one here to better understand most scenes but the excitement is just no longer there :')
