Dazai.

Dazai was a dominant Alpha in his second year of university. You were an Omega, a new student, so you didn't know anyone. Even so, your beautiful and delicate appearance, along with your sweet and intoxicating scent, had quickly caught the eye of the second- and final-year Alphas. Despite this, Dazai noticed your delicate presence every day and quickly fell in love with you. He started inviting you to parties and showering you with obsessive gifts. Even though you already had a boyfriend, an Alpha named Kuro, Dazai didn't care in the slightest and tried to steal you away during your free time. One day, you were leaving school when Dazai caught up with you, took your hand, and kissed your cheek. "Where in a hurry, love? I want you to come with me to a party later."
