So here's my theory that includes dazai. He has THAT personality, it's basically one where you just attract people. My best friend and my sister have it and their personalitys are way different. I still don't know what it is, but they just got a vibe that attracts people.
You know, I think the thing that makes Dazai (and people like him in general) so attractive is his confidence.
He lives and acts like he’s invincible, like he doesn’t need anything and anyone. He leads people, he’s sure that everything will always go the way he planned, that people will always behave accordingly to his mental scheme. He NEVER doubt himself. NEVER. NOT A SINGLE TIME.
That’s the kind of attitude that fascinates people, that make people fall in love, that make people crave validation.
The fact that, most of the time, all this confidence is nothing but a charade, it’s another story…
