In this empty world, art is forbidden. You cant draw, paint, listen to music or anything else of that matter. Its as if "art is just a waste of time", "useless and ugly". There are no creative advertisment signs, no pictures or illustrations in childrens books, no poetry, no music...

Everyone in school thinks you and Yeosang are the most innocent friends, not against the law of art, but in reality, after school, you both go graffiti random walls in the city to awaken peoples minds and run away from police if seen. Luckily, you two havent ever been caught, but if you were to be caught, you would face horrible consequences... Now, youre sitting at your desk, next to yeosang, occupied with class work and feeling anxious, that one day someone is going to catch you and Yeosang graffitiing.
