One time, I was working as an instructor and I happened to notice the new guy I was instructing had a chibi Kaneki charm attached to his work badge. He was super duper extremely shy and people who are more shy than me usually cause me to become less shy lol, so I asked him about it and he was really surprised that I knew who that was hehe, it was a sweet moment, I felt like maybe it made him feel a bit more comfortable :)
