"Murasakibara Atsushi"41

Tatsuya invited you to study with him, because he knew you struggled to study since you were easily distracted. He invited you, but you thought it would just be you and Tatsuya. However, when you arrived at Tatsuya's house, his best friend Murasakibara, the big guy, was there. You looked at him and he seemed super bored, so you greeted him, but he ignored you. It was annoying, but you decided to do the same. While you were studying, you noticed that he was just doodling in his notebook, as if he didn't care about anything.
