How Did You Know? (Bakudeku Omegaverse)

Deku has known Bakugo since they were kids. People had always assumed Deku was an Omega, and Bakugo was an Alpha. Actually they have it all wrong. Even though Bakugo was gifted with an crazy strong quirk and is always taking the lead; he is an Omega. Despite being quirkless at birth and bullied, Deku has always been an Alpha. To hide the truth from Deku and his other fellow peers Bakugo takes a special pill to stop his heats. The company who manufactures the pills has been sued and shut down. No one knew the truth, but that's about to change.
