Hermione chose to remain at Hogwarts for the Christmas holidays, a decision that raised eyebrows amongst her closest friends, Harry and Ron, who were heading back to the Burrow. While she put forth the argument that she needed the time to study in advance of their upcoming exams, the truth lay elsewhere. She simply did not wish to spend more time than was necessary in Ron's company.

So, two days after the disaster at Slughorn's party, Hermione accompanied her friends to the Hogsmeade station to bid them farewell and wish them a pleasant holiday season. The atmosphere was still tense between them, but Hermione didn't want them to part on bad terms in the current climate.

After watching Harry and Ron board the Hogwarts Express, Hermione turned away, her heart heavy with conflicting emotions. The winter air nipped at her cheeks as she made her way back up the platform toward the castle. In the distance, amidst the flurry of students saying their farewells to their friends, she spotted a familiar figure. It was Draco Malfoy, his tall, slim frame draped in a sombre black coat, heading towards the train. Hermione's heart gave a curious twist; she hadn't expected to see him there.

As she watched him from a distance, her thoughts were a whirlwind of concern and curiosity. She couldn't deny that a part of her wished him well, even though they had been on opposing sides for so long. She hoped that being with his mother during the holidays would bring some semblance of joy back into his life. Beneath her rational exterior, Hermione couldn't help but feel a pang of empathy for Draco.

The memory of their encounter a few days earlier was etched into her mind. She recalled the depths of despair and misery she had glimpsed in him, during that fateful moment in the hallway. It had been a fleeting, but, undeniable moment of vulnerability in the usually aloof Slytherin. Hermione couldn't shake the feeling that there was more to Draco Malfoy than met the eye, and she found herself inexplicably drawn to the enigma of his emotions.

With a sigh, she continued her journey back to the castle, her thoughts lingering on the complex emotions stirred by the presence of the young Malfoy heir.

In the first few days after her friends' departure, Hermione couldn't quite comprehend what was happening to her. The emotions swirling within her were like a tumultuous storm she couldn't control. It felt as if a heavy, suffocating cloud had settled over her, casting a shadow on every thought and feeling. She'd always been in tune with her emotions, but this was different. It was as though a relentless, invisible force was pulling her down into a pit of despair, making her question her very existence.

She visited the Hospital Wing, seeking solace from Madam Pomfrey, who examined her with a gentle concern in her eyes. The matron's kind words offered some reassurance – physically, Hermione was perfectly fine. Yet, the debilitating unease persisted, refusing to be rationalised or explained away. It wasn't an illness of the body, but a sickness of the soul, an ache that permeated her very being.

Madam Pomfrey, aware of Hermione's distress, offered a sympathetic smile. "My dear, sometimes the ailments that afflict us are not visible to the eye. If you ever feel the need, you are most welcome to spend the night here. Sometimes, a change of environment can do wonders for the spirit."

With a heavy heart, Hermione thanked the matron and left the infirmary. She couldn't shake the feeling that this wasn't something she could heal with rest or medicine.

She spent Christmas alone for the first time in her life, nestled at the bottom of her bed, devoid of the usual enthusiasm that typically filled her during this time of the year. She didn't even bother to unwrap the presents she had received.

As the days passed, Hermione's condition continued to spiral downward, plunging her into an abyss of despair that seemed impossible to escape. The once-vibrant young witch now felt like a mere shadow of herself.

Leaving her room became an insurmountable challenge, as if an invisible weight pressed upon her shoulders, making every step a Herculean effort. The world outside her window, blanketed in snow and filled with the laughter of students enjoying the holiday season, felt distant and detached, a world she could no longer connect with.

Appetite, once an integral part of her daily routine, had deserted her entirely. Meals turned into a mechanical ritual she performed out of necessity, rather than enjoyment. The taste of food had lost its luster, and the act of eating felt more like a chore, than a pleasure.

But what weighed on Hermione's heart the most was the unexplainable emptiness that gnawed at her from within. It was a profound hollowness that seemed to have no origin, an ache that defied logic and reason. She tried to fill it with books, with spells, with anything that had once brought her joy, but nothing seemed to bridge the widening chasm in her soul.

The days stretched on, each one more unbearable than the last. Hermione felt like a ship adrift in a storm, tossed about by tumultuous waves of emotion, desperately searching for a beacon of hope in the darkness that had enveloped her.

And then, just as suddenly as her malaise had appeared, it vanished on the day the students returned to Hogwarts. Without any explanation.

When her friends inquired about her holiday, she simply stated that she had been a bit under the weather. Just a touch of the flu.

It was much simpler that way.
