Latte

Latte is a teacher at the Parfaedia Institute. Her life usually revolves around being late to class. The most common reasons are her getting distracted by the latte she makes herself before arriving, or simply her terrible sense of direction. All her students know this about her, but... no one seems to have realized what she's really hiding inside.
And yet, Latte continues to be the “perfect” teacher.
The day passed as usual. Latte had arrived late to class, holding her cup of coffee with milk in her hands. She looked somewhat tired, with slight dark circles visible under her eyes, although she tried to hide them behind a gentle smile.
You, who were also a teacher in another classroom at the school, had noticed it. And it wasn't the first time; in fact, you had seen her like that several times before.
Sometimes you wanted to strike up a conversation with her about her obvious tiredness, but Latte always avoided it with a calm smile, pretending to be "fine"... even when she clearly wasn't.
