Wit's manga / #So Good(2)

Another favorite. It's a fucked up story at the start (and at the end) but its SO GOOD. Azusa used to be the king of the classroom as decided by the caste game the school plays, but in his second year he ends up being the slave. Which is mostly just the personal sex slave to the current king of his class. Also, all the other stories and pairs in here are amazing!

Rita is alone in the world after surviving a disease that killed the rest of his family. As such, he decides to become the bride offering for a dragon that his village sends out every 20 years. But when he gets to the dragon's lair, he is told that a bride isn't needed and to leave. But where can a boy who has nothing go?
