Y/n gets into a lot of fights and I mean a lot, nearly every new shift he has new cuts or bruises from fighting but y/n is also very fucking good at their job and that is being a firefighter with the 118. They don’t knwo much bout y/ns past but jsut knwo it’s bad, y/n has an ied (anger issues) and y/n never take their anger out on they family (the 118) until one day things get some bad and y/ns pass coms knocking. Buck tries his hardest to calm him down and keep him calm. Y/n also sleeps with a lot of people like Buck 1.0 did
