This one-shot is difficult to describe, because it's unlike most manga I've come across.
While there seems to be no backstory, or much storyline in itself, from the conversation, confessions and apologies these girls pour out in only 20 pages you get an in-depth knowledge of their personalities and relationships. While the story seems to by completely dialogue driven, the art is quite well done, and some panels are really emotional given you barely know what's going on. For sure, it's one you'll have to read a few times to fully grasp, but that's what makes Truth interesting! Not bad but not really great either :P
