Cozy Obsessions (2024)

Blurb:
Huimin Seo happened to read a tragic BL novel where the two main characters had both his name and even his best friend’s name, Iheon Cha. But rather than remaining as an incredible coincidence, this book becomes a new reality for Huimin. Before he knows it, he is transmigrated right into a major scene in the novel where Huimin Seo, a rare dominant omega, gets bought off in an auction by Iheon Cha, a powerful dominant alpha. Aware of the complications in this love-hate relationship that he cannot escape from, Huimin must tread carefully to turn things around entirely.
