Bruises and Bitemarks
Biologically, Stiles is weak. When he presented as an omega, he knew that to be the truth but that never stopped him from running his mouth as a defense mechanism. However, it could only save him so many times before he ended up pissing off the wrong person. After he's attacked in the parking lot outside of school, Stiles realizes he can no longer protect himself with just pure wit and sarcasm. When the attack lands him in the hospital, his dad forces him to pick between two options, report the alphas who attacked him or join a kickboxing gym run by omega rights activist and alpha, Derek Hale, a man Stiles has been in love with for many years.
