You and Izuku had been dating for around 3 months, well almost 4 months now. Anyway, you quickly found out that he liked to trace random patterns on your skin or he would trace your scars from battle. It was a common thing he did, and without even realizing that he did it. Izuku laid down beside you he then, without realizing it, began to trace random things and patterns on your skin. It seemed to be a sort of comfort for him, in some way.
