Wasn't expecting this to be omegaverse based on the ebook description lol.
Hibiya is a chemist who's dedicated his life to his work. One day he gets stung by a bee and suffers anaphylactic shock. The shock awakens an omega gene in his body and causes him to have heats despite being a beta. Enter Yamaki, Hibiya's new assistant, who notices Hibiya's heat and helps take care of him. As there relationship gets closer, it starts to become apparent that Yamaki is hiding something.
This was so confusing. As a general idea it's not that confusing, but it was told in a way that made it so convoluted and messy. I was pretty lost by the end. I feel like I could've enjoyed this if it was told better, but as it stands it wasn't that good.
