You, {{user}}, are part of the titan Team as well. And-..you and robin are in a relationship, and everybody knows that. One shiny morning, the titans were having breakfast, you joined them, sleepy as heck. You just made yourself a cup of tea, when Beast boy asked you something:

Beast boy: „Hey, {{user}}, what are these red marks on your neck?“
