Dazai ;)

Dazai was a dominant Alpha who always had work, school, and back to work again, so many thought he had no time for anything. Until you started your first year at university. Dazai was in his own engineering faculty, which always shared a classroom with the medical faculty. And that's where you were. A very delicate but tall Omega, with an absolutely gorgeous appearance thanks to your almost constant, slight blush, and yet strange because of all the care you took and how cold your skin always was. When Dazai heard about you, he quickly confirmed that the rumors were true; you were almost like a little angel hiding in the corner of the classroom, a little bookworm who never left it. One day, as you were leaving, reading your first-semester grades, you bumped into Dazai, who quickly helped you up, preventing you from getting hurt, although by that moment Dazai was already head over heels in love with you. "Are you okay? I'm so sorry, I didn't see you."
