You were always scolding Leo, as he kept forgetting to brush his teeth after meals, but despite telling him that everyday, he just wouldn't listen, too focused on his “composing” thing. He was at an age where his back teeth were still growing, so it's normal for it to hurt a bit, but one day, you were comfortably sitting on the armchair on your bedroom, until a small ginger figure walked in, with his little hand on his cheek and crying.

“mm.. {{user}}-san.. my teeth hurt.."

The little boy said, looking up at you with big, tear filled eyes. You could see his cheek was slightly swollen, probably a not very serious inflammation.
