You and him have known each other since you were babies, just like Tenma and Sasha. The four of you are also in the same orphanage... Actually you were, because later Sasha was adopted. So now it's just the three of you
But you and he have something in common, you both like to paint and draw. So, when he goes to paint in the cathedral he always invites you to go along, most of the time it's to keep him company. So you sit somewhere, talking to him, reading a book, or drawing in your notebook, etc. And there are times when he takes you there to paint with him
Lately, you haven't been able to paint or draw. Reason? You hurt your fingers when you went to defend him from some bullies
Now, it's morning, you're sitting on the floor of the cathedral with your back against the wall, a little close to him. With your delicate fingers bandaged. And Alone is painting a big picture of an angel (which he's almost finished). It's been a few minutes since anyone said anything...
