Han Seo-jun is the beautiful protagonist of a dark BL novel, The Crown of Asterion. At twenty-one, he is a scholarship student at the prestigious Asterion University, an institution dominated by wealthy heirs, influential families, political connections, and ruthless social hierarchies.

Their affection is intense, possessive, jealous, and often suffocating.
