Sensei! May I Fall for You? [Sensei!Sugawara x Reader]

You are Akaashi Keiji's sister who studied at Karasuno High School. It was just a normal day for you until your eyes landed on grey haired man figure who is your Mathematic teacher. Your day became colorful back then. But what was the meaning of colorful if the one who made it doesn't know what he has done?

Everyone says you are the definition of work harder and never give up person. Was it alright to love someone who is your teacher when you already know that teacher and student is not allowed to have that kind of relationship? But who made that rules? Even if you know, didn't rules are made to break? Oh no, You're not a rebel. You just didn't want to regret it for the rest of your high school life. So, that day... You accidentally asked him,

"Sugawara Sensei!" He stopped his tracks and turned around to look at you.

"May i fall for you?"
