It's funny to think that Taichi mentioned the 'Troupes' in a horror movie. I'm not a big fan of stockholm syndrome story but maybe I'll give it a chance since I have nothing to read.
The Stockholm Syndrome troupes such as killing stalking, warehouse, and etc have been famous. The fandom of each of this manga/manhwa has mixed reactions towards this kind of love story. I hope the ending will be satisfying. (▰˘◡˘▰)
