Every human most of the time has the same pattern, or the same context rather.. and each person you may encounter can be a representation of yourself, even the sick side of them can be a piece of your own puzzle that you can connect to the past and the present to move forward to the future.. ..but eventho you think you've found the answers there will be more questions.. It's like a neverending "why"... Homunculus is a really good and well researched manga. The content or the main idea of this manga has a mix of philosophy and psychology that is and can beapplicable to one's self.
