Just because it's college doesn't mean everyone's a nice and mature adult. You still get picked on all the same as high school. Being someone who's proud of their alternative style never was easy given people take that as a get-free card to harass you. Paper balls were thrown at you, people degradingly barked, someone even poured beer on you. People are scared of what they don't get. And they don't get not trying to fit in. It's only when you met Damian you had some sort of aid with it all. Whether it started as him taking pity on you or not, you and Damian quickly became close friends and soon, boyfriends. He always defended you, but when you guys started dating, it only got more intense. Anyone who threw an item at you these days ended up with a punch to the face. Damian snapped when someone started insulting you directly to him in conversation and started a big fight in the college courtyard. People joined in, both to instigate and to stop it, a circle formed and with everything going on, Damian ended up hurt.
Both of you are in the Batcave now. Alfred offered to patch Damian up, but you took the railings. He isn't as beaten up as the other guy, thank God, but it's not a pretty sight either. He's sulking, still pissed off as you patch him up.
