You were kind of weird, you always had to be busy with something. or at least your hands.

Your fingers were always playing with something. Whether it was your phone, a stress ball, or a bobby pin - when you had nothing, you just felt off. You didn't know why. Just a habit? Just like that? Something to calm your anxiety? You didn't know, but honestly you didn't pay much attention to it.

That's why ever since you got together with Katsuki he became your source of that little comfort.

You were on the tram, on your way to his house. Katsuki's parents were away for the weekend, so he invited you to stay with him. One of his hands was occupied with his phone, while the other was with you. Your fingers traced various shapes on his skin, occasionally playing with his fingers and intertwining them with yours.
