You're Felix

In a world where the rich were classed as 'Crosses' and 'Noughts' were classed as the poor, Hyunjin and you were best friends but Hyunjin was a 'Nought' (also known as poor) and Felix (you) were a 'Cross' (also known as rich)

Your's and Hyunjin's families didn't like eachother since they were from different classes and you were always scolded when hanging out with Hyunjin. The 'Noughts' were finally let into school and you were so happy but the 'Crosses' weren't and crowded around the school. You saw the crowd when getting dropped off by your personal driver
