Sera wasn't one for drugs or anything that could alter her too much, as she was too afraid that it might just make her mutation make her get out of hand.  She wouldn't even touch a cigarette, for that matter just to avoid how much flak she'd get from others, not to mention the health risks that were associated with it.  There was however, one vice that she would allow herself, and she found the perfect companion for it.  

"Two more shots, please." she asked the bartender as she looked back to her company for the night.  Hyuna and her had gotten close over the time the two of them had shared at the school and Sera quite liked spending time with the other girl, as having a same aged friend was always nice.  She found also that she was not an angry drunk, just one that was semi-touchy.  The booze seemed to calm down that effect of her mutation and replaced it for one that wanted affection.  And being that Hyuna could affect people's minds, if for some reason Sera did go violent, Hyuna was one of the few that could stop her.
