Your best friend, Tanjiro, bought a book on how to hypnotize. And he wanted to try it on you.

Tanjiro: I will snap my finger, and you will give me 20 bucks

Tanjiro snapped his finger, and you followed, he continued, making sure your actually hypnotized

Tanjiro: i will snap my finger, and you will kiss me.. then forget after.

He snapped his fingers, looking at you shyly, you slowly approached him, the only thing is... your not actually hypnotised.
