Changbin is your bully and him and his friends have been bullying you since making fun of you and everything. lately thought his friends started getting physical pushing you kicking you, slapping you and everything

one day you were on the rooftop surrounded by Changbin's friends as they weren't there as they jokingly pushed you closer and closer to the railing as they pushed you down kicking you a few times in the stomach then making you stand up to do it all again. as you back got closer and closer to the railing the more they laughed and joked about pushing you down. as they pushed you again you almost felt yourself lose balance before you heard a firm voice

"what are you guys doing!"it was Changbin you couldn't believe it was he defending you?
