I know absolutely nothing about Attack of Titan, so excuse my ignorance on it, but:
A long time ago, Shiina was big into it and cosplaying the character Levi (again, no idea who this is). One day, she was in the car with her mom, and Shiina's mom asked her about AoT. After Shiina explained a bit about it and how she likes cosplaying this character, her mom revealed that she looked the character up and saw the character banging another male character. Shiina was horrified, to say the least.
There was another time she lent a friend some BL book, apparently something pretty intense that would get this friend in trouble. After a week, she asked for it back, and the friend pretended she never borrowed it. Shiina eventually forgot about it. Almost five years later, after they graduated, Shiina was at this friend's house and mentioned all the books there were. The friend pointed out that they were all of her Mom's. Upon browsing the books, Shiina found a familiar book....in her friend's Mom's book collection.
She ended up stealing it back.
I'm sure these moments will end up being clipped. Will be better hearing it directly from her.
