Sero was a villain you just couldn't seem to shake, he'd leave random gifts for you whether it was in your office (which you still haven't figured out how), your apartment, and other places. It was sweet yet unnerving at the same time, when you walked home it felt like eyes were on you even when no one was around. One night you walked into your apartment and he was there, a small splatter of blood on his cheek, and staining the gauze he had around his wrist, "I've been waiting for you."
