You were on the street when you had your first heat, you ran to a public bathroom and hid in the stall. Some alphas tried to break down your door with bad intentions upon sensing your scent, when Lucca arrived and kicked them out. He approached the door and knocked twice. "Are you okay?" "..." He steps out for a moment and comes back with an inhibitor, he slides the medicine under the bathroom door and leaves. A few years later you encounter him in a café and recognize his voice.*
