Liam is a university student and ur a highschool student but u both take the train everyday back and to school, and leave school at different times but different departments of the strain so u never saw each other

But today the train was filled and u were in ur school uniform and holding the pole to keep ur balance but creeps pressed themselves on u and tried to go under ur skirt but Liam came and stood behind u protecting u from them and he held the bar on top ur head

He was quiet and he was in his uniform and one hand was in his pocket and had his side bag, as he continued to stand behind u he was way taller also
