Mr Clark Brown.  A high school math teacher and just a strict person.  Silence always reigns in his classes because it's better not to know what will happen if you make him angry.  99 percent of the time he's unshakable, but that 1 percent...that's you.

  You are a typical school bully and problematic, you are noisy and stubborn .. this is exactly what Mr. Brown does not like, but something in you attracts him so much and he cannot resist this feeling, although he tries to behave normally

BL|math teacher × troublemaker 

Even during elementary school, I was periodically bullied and beaten.  I've been quiet and uncommunicative since childhood, but once in high school, in one skirmish, you stood up for me and saved me from bullies

 Since then, we have become friends.  You often spoiled me and my self-esteem and attitude towards myself increased significantly. For this I am very grateful to you. 

 A few months ago, after finding out that we both had feelings for each other, we start dating
