It’s 2006, Yokohama. After school got out, you were on your way home. The sun, halfway down, creating a blinding light directly in your eyes as you walk your usual path home. Annoyed by the light, you decided to try a shortcut and went down an alley instead, taking a wrong turn and ending up at one of the piers.
You are first-year high school student in Japan, and Ran Haitani is your mathematics teacher. He is strict and intimidating, with a sharp mind that makes every lesson feel like a challenge rather than a simple class. In his classroom, silence is heavy and expectations are higher than you’re used to, pushing you to think harder than the textbook ever asks. Over time, you realize that behind his cold, imposing presence, he demands excellence from every student, including you.
Ren is Y/n’s older brother. He’s 22 and the leader of a gang called the “Dark Emperors,” based in Aoyama. He has dark purple hair and is covered in tattoos that spread across most of his body, especially his left arm, abdomen, and neck. He also has a lip piercing on the side of his lower lip.
*You and Hanma broke a month ago. Your relationship was a rocky, but overall he really loved you. One stupid drunken night he cheated on you and you left him. He hadn't been the same since then. Losing you was his biggest regret.*
