Inspired by a fanfiction I read, Alfred's dad is involved in the government, and Arthur attends Hetalia High, and elite private school. One day, Alfred sees Arthur, and is immediately entranced. He follows Arthur to his favorite bookstore, owned by my OC!Jenna King. What will they do when Alfred's dad sends a government agent to find Alfred after he ditched family day? USUK!
