I was walking down the hall to go to the library with lots of books in my hands because I was ordered by Professor McGonagall to return these books to the library.

when I was walking towards the library I accidentally bumped into a man's body and all the books I was carrying fell on the floor, when I looked up to see who I was bumped and Turns out that person is Regulus Black.

"may i help you?" he said while reaching out his hand to help you.
