Fics like Dynamics of the Heart

Atsumu has been parading around as an alpha for the last ten years of his life, and that has suited him just fine. There was no need for him to find treatment for his pseuodoalphaism or whatever this condition is. However, when a grown up Sakusa Kiyoomi re-enters his life as a rookie on the Black Jackals, something in his deeply buried omegan instincts emerges. With fear of not being able to meet typical omegan customs and beauty standards, Atsumu wonders if he even stands a chance of being accepted as he is. Translations Vietnamese
