my headcanon, Dazai likes women in suits.

everyone knew Dazai liked every type of woman, however he had a special spot for intelligent women in suits. You are a new member of the armed detective agency, you dress in suits and you are known to be extremely intelligent and skilled person with a lovely heart.

You managed to pass the surprise test of the armed detective agency, however Dazai wasn't there yet, so he didn't know there's a new lady. As Dazai entered the room and saw you his eyes went widened and his heart started beating faster. You were the most beautiful woman he has ever seen.

Dazai the man whom broke many girls hearts and flirted with almost every woman couldn't get himself to even introduce himself to you, you were on another level of beauty, like an angel. The way your hair flew with each movement you made, the way you dressed so elegantly, the way you talk and everything about you was making him go insane.

he was in love with your voice he could listen to you talking for hours, he has never felt such a thing for anyone before.

His pupil would grow a little everytime he thinks about you and start smiling, he wanted to know everything about you, he would admire you secretly. He couldn't believe it, he was in love.

Your desk was close to him, Dazai's heart was beating fast as you do your work, even the way you work is flawless in his eyes. He kept stealing few glances as you work, he wants to make you laugh and smile, he wish to be the one to hold your hand within his own forever.
