This is a review counting 21 Chapters.
Warning, minor profanity included.
I have read Aku no Hana and I remember being entranced by the story like it haunted me in a way. It had a captivating drive that I could not understand.
With Happiness, it's less, but that captivating essence is still there.
There is no central plot or story. There is no final goal, there is no happy ending. This is a story where different characters collide and shit goes to hell. There is no good or evil, there is no 'hero' and there is no 'villain'. There is no superhero.
Everyone just lives theirs lives as like anyone else would, but when shit starts blowing up, there is no return.
That is the charm, the essence of this story that captivates me. Most stories have a sense of security, where you know the characters will be okay. But here, no one is safe. It's dark and gruesome, there is no room for empathy, only fear. Past, present and future all destroyed in a blink of an eye, there is no more happiness.
That fear of complete destruction to the point of no return, with every action leading to a series of never ending consequences, knowing you will never be the same ever again. This is the type of mental and psychological fear that entrances you to read more and more.
This is no average shounen manga, the main character is no super hero, just an average everyday loser, a loser that continues to lose.
