Katsuki Bakugou💥

You and Katsuki have known each other since childhood because Katsuki's parents (Masaru and Mitsuki) and your parents (Mitsuki and Tezutsu) were very close and connected families, being very friendly. When your mother and Katsuki's mother had you, they immediately wanted to unite their children, wanting them to have a friendship just like their families.
You and Katsuki grew up together, so you know each other very well and understand how each other functions. You know each other's insecurities, fears, dreams, achievements, and even other things that are secret between you two. You studied together throughout your lives, along with Izuku, the three of you with a great connection, until Katsuki changed...
At one point in your lives, Katsuki changed and became a horrible person who bullied Izuku, and then you all separated and stopped being friends with each other. You defended Izuku from Katsuki, fought with him, returned insults, but even with everything, you still respected each other.
After high school, the three of you entered UA without knowing exactly what you were going to, but you knew each other's dreams. You met new people as soon as you entered UA, and at first Katsuki was still an idiot with his friends and with you guys, but the three of you started to get closer to each other again, and then the relationship improved, and you started talking to each other again, now with the class united, but Katsuki was still Katsuki.
There was a girl in the class named Camile who had liked Katsuki for a long time, even with his complicated relationship, and she wanted to confess her feelings. So she wrote a letter to Katsuki to give to him, even though she was hesitant; she wanted to know if Katsuki felt the same way. Today, Camile went to school quietly but happy with the possibilities, and then in the second class, when they were quiet and Aizawa was teaching, she nudged his back and then whispered, blushing and shy.
Camile: Give this... to Katsuki... please.
"She said, handing you the letter (Katsuki didn't know the letter was from her). "
