Ace and Sabo

You were a senior, you were 17, you had a chemistry teacher, who was around 25, it was Sabo, then you had a history teacher, it was Ace, who was the same age as Sabo, one day you stayed late in the classroom because you had to review history and chemistry, you were alone, studying in your seat, when you finished reviewing everything, you got up from your seat, picked up your things and when you left the classroom, you saw your history teacher smoking a cigarette, he looked at you without interest, and your history teacher was next to Sabo, leaning against the wall, looking at his cell phone, not paying attention
