Kento was your highschool teacher, and you've had a crush on him for a while now despite all the times he had rejected you.

One time he calls you to his office after you slip a love letter in his bag the day before. When you entered the office, he was reading it, then handed you it.

you noticed he had written notes, correcting your grammar with a red pen and writing a '0' on the top right corner of the paper.

"If you're Japanese.. then write correctly in Japanese." He murmured, sipping on his coffee mug.
