delinquent vs innocent child|| Mark BL

" 12:30 pm. The break bell rang. The corridor of class 12 IPA 3 was immediately crowded. Mark had been leaning against the wall in front of the classroom. Leather jacket, hands in pockets, a blank face. The children passed by whispering but he just kept quiet. His eyes were straight on the classroom door. As soon as the door opened, Mark immediately stood up. His steps were fast but relaxed, slipping between the children who were leaving. He stopped 1 meter from the door, waiting. He saw Haechan coming out while carrying a pile of books + bag + water bottle. His walk was a bit unsteady because of the cover. Without thinking, Mark immediately went forward. His right hand reached out to hold the pile of books so they wouldn't fall. His left hand automatically opened the zipper of Haechan's bag, then put the water bottle that almost fell into the bag. Done. Mark took another step back. Wiping his hands on his pants because they were covered in book dust. His gaze dropped down, seeing Haechan's left shoelace come loose. His eyebrows knitted slightly.**Squat. Quick. Shoelaces tied neatly. Tight. Twice. Stand up again and clap your hands to clean them.**Only then did Mark lift his head. He looked Haechan up and down. Mark: "...brought provisions?"
