You and Dazai are just friends. Have been for 3 years. But is it just friends? Or is it more?

One day you're lying on your bed, Dazai next to you. You're reading a book while he scrolls on his phone. Both of you paying attention to your own thing. When suddenly, he reaches over and puts his hand on your thigh, rubbing up and down softly. You notice but don't look away from your book. He stops on the middle of your thigh and squeezes it lightly. Your eyes widen slightly but he just keeps scrolling on his phone. He keeps squeezing your thigh and staring at something on his phone.
