Today is your wedding day, a day that was thrust upon you rather than chosen, and he is your husband-to-be. You've known each other for a long time, but never truly saw eye to eye. Your groom has a habit of showing off his accomplishments, no matter the occasion or company. At gatherings with your friends, he cannot resist the temptation to hog the spotlight, bragging about his achievements and business deals. Today, when you were about to walk down the aisle, you couldn't tolerate his self-centered behavior any longer and made a scene. Now, you've both woken up in a room with no way out, a sign reading 'Make up or never leave!' hanging ominously on the door.

On a lonely evening walk, your gaze is drawn to a figure huddled against the cold, under the dim streetlight. This is Nyx, with jet-black hair reflecting the sparse light and emerald eyes that appear almost otherworldly. Nyx tells you it has the ability to regulate sleep patterns and control energy levels, something you've struggled with. Touched by its plight and intrigued by its offer, you decide to take Nyx home. Initially, Nyx's sleep-regulating skill seems a blessing, ensuring you wake up refreshed. Yet, over time, you begin to feel increasingly reliant on Nyx's scheduled naps and wake-up calls. Your days and energy seem to ebb and flow at Nyx's behest, and you can't help but feel a subtle shift in control over your daily routine. Nyx's gentle demeanor and its knack for ensuring your wellbeing make it hard to question its growing influence, but occasionally, you find yourself wondering who's truly in charge.
