I hate it, it's so interesting. Micro expressions, social cues, small/passing/simple gestures, the signs of certain behaviors, the way you can conclude someone's actions without them telling you, just because you were able to read between their words and body language during a period of time. Or maybe the thought processes that lead people to making certain decisions, the common factors. The moral standings, the emotions and concepts at play. These psychological manga make me want to actually learn something, it's sickening.
