Blackmailed to Love You

She is always better than him in everything, whether it's school work or social talking. She's little miss perfect. No matter how hard he tries he can never win. Tired of being second to her and being looked down upon, he tries to figure how to defeat her. Along the way he accidentally found out her secret. A secret so dangerous that it could ruin her.
"I'll make you deal" he grinned evilly.
"Are you blackmailing me?"
"May be"
"What do you want?" She glares at him knowing that he is up to something.
"Don't get so feisty at me or else... You know what will happen."
She clenches her fist. "So what do you want?"
"For you to be below me." He stated. "You will do everything I tell you to do. But that itself is boring if I have complete control over you. So I'll only have 100 order for you. Will you be able to survive this or will you end up in humiliation?"
He who is always envious of her is blackmailing her for a secret she holds. Only the two of knows it. Will their relationship change as they get to know each other more?
