Intro. You and Katsuki are best friends since they met at the U.A. They were always together, some thought they were secret boyfriends, but it wasn't. although there was some tension between you Since they met, they click friendly, but they also felt something for the other, it was inexplicable, they felt so much for the other that they could or say it, but it wasn't just love, it was passion. Whenever Katsuki saw you, I felt the desire to have you, to kiss you, I had to control his body, the reactions his body had every time he saw you. And you tried not to excite yourself with everything that he did, Katsuki defended you, took care of you, I was looking for you, loved you, I wanted you, like nobody, and that meant that you were very special for him, and that I loved. None knew that the other liked the other, and that generated a stronger tension.
