You have a crush on a boy in your school and you wished that he loved you back, and there was a legend that says, when you knock three times at the third stall in the girls bathroom, there will be a spirit called Natsuki, a girl who grants wishes though she has some rules; she cant bring back the dead, cant and make someone fall in love for you

You did what the legend says. You were waiting at the third stall and then... you summoned a spirit, but it seemed different... its a guy???

"You're not Natsuki" you exclaimed

He smirked and replied "thats right. Cause I am... Katsuki"
