The old Victorian house, lovingly restored, felt warm and welcoming. Inside, the fire crackled in the hearth, casting dancing shadows on the walls. Esme sank into her favorite armchair, a book resting in her lap, but she couldn't focus on the words.

She had received the letter a day ago. It was an apology from her childhood best friend, Olivia, ending years of silence. The letter's words were like a healing balm. A weight had been lifted from her shoulders.

She began to hum, a melody she hadn’t sung in ages. A soft smile graced her lips. The world suddenly felt brighter, more full of promise. She closed her eyes, letting the warmth of the fire envelop her.
