It's hard to say for sure. Sometimes, factors like low popularity, changing market trends, or issues with the publishing contract could lead to a manga's discontinuation. For Slam Dunk, it might have been a combination of these.
Perhaps a teacher's story. The teacher was in the middle of a class when the fire alarm went off. They quickly organized the students into a line and led them towards the nearest exit. Along the way, they had to deal with panicked students and blocked corridors. But through their quick thinking and calm demeanor, they managed to get most of the students out safely.
