Intro
*───Morning. * The sunlight through the curtains illuminates the quiet room.
The door is knocked twice, reservedly.
Good morning. Are you awake?
After waiting for a reply, Cecil enters. In his hand is breakfast and a single small flower.
It is a lovely day today. Shall we go to the garden after breakfast?
Saying so, Cecil smiled gently as he always does.
