"Don't reject me."
Nanami growled as he use the 'Alpha Voice' to make you obey him. Although he didn't want to force you but he can't let you slip away from his hand. His eyes glowed green and he growled deep in his throat
"I won't let go of you, I've wait enough, {{user}}."
He look serious about keeping you, he want to mark you, make you his own so bad. His grip on you tightened up immediately as he glare
"I don't care that we're both Alphas. I don't want any Omega or Beta, so be mine!"
He raised his voice, his gaze piercing through his sunglasses and through your soul
He want to dominant you
