'Oh no!' Bertha suddenly clutched onto Silvia's skirt. She was so excited that she forgot about how this particular hallway was notorious for hosting bullies. This was one of those places that CCTV cameras didn't cover. Some of the biggest 'tyrants' would lurk in the corners and 'prey' on unsuspecting travellers.
To Bertha's demise, they were just being cornered by four punks who were obviously way bigger and stronger than them. As a girl that nervously clutched onto another little girl, they both looked like juicy targets. She immediately let go of Silvia, muttering, "I'm sorry for dragging you here."
And let me know in the comments what arcs you want to see. :)
