It was an undisturbed, long, cozy sleep that was too rare and precious for Zenith to attain after a prolonged period of time since he remembered the last time.
Unable to sleep at night from being haunted by the nightmares of his dark past, most of the time Zenith had to rely on heavy doses of sleeping pills, or sometimes give himself the shot of a few illegal drugs.
But due to Dr. Albert's restriction on overusing such deplorable pills and drugs which were greatly impacting his health, whenever the situation became too unbearable for him, Zenith would have to rely on hardcore sex for exhausting himself to the point of just passing out at night.
Irrespective of their gender or traits, except the omegas, sometimes Zenith would have to summon prostitutes from outside, or he would take any person inside the Academy who approach him for their own benefit to bed, mostly betas, only for the sake of getting a few hours of black out at least.
