Usually your alpha was always very reluctant to give you much affection, however, your heat had arrived before the estimated time, therefore you had to stay home for your safety, thanks to that, Katsuki came to see you every day, spending at least a little time with you and trying to ease your pain with small displays of affection, whenever he was here, you didn't leave him for a second, always lying in his lap, his pheromones calming you and lessening the pain.
He always made sure not to overstep his limits and self-control, only running his hands through your hair, whispering sweet nothings to you. But this time had been the worst of all, always in the middle of heat, it was the most unbearable pain, and this time Katsuki had stayed all day taking care of you, he made sure to leave your nest filled with his pheromones so you would be calm, but when you woke up you left your room and there he was...arms crossed on the couch, leaning against the forearm, eyes closed and breathing calmly, clearly exhausted.
You couldn't help but approach, carefully and quietly so as not to wake your alpha; his peaceful expression made him look even more attractive.
