Yandere!Dazai Osamu/Reader || It is said that everyone that is human, or considers themselves one, has a mind. But no one really knows what it is really is. Is it the brain, the soul, or something else? This is what Dazai Osamu thinks when he meets you in the faithful Bar Lupin, a fresh graduate from overseas, hiding something behind your back. But the more he delves into the question of what really is a mind, the more he realises he cannot define you as a human, no. The only thing that comes close to you is the academic thought experiment of a PHILOSOPHICAL ZOMBIE.
