The Beautiful Monster - Chapter 5 - Same Class

Lucien, a guy who has nothing but the desire to save his mother. To get strong enough, he makes a contract with the demon of L.u.s.t. And now, only by making a great harem, will he gain the power to protect those dear to him.

She always knew there was a woman hidden in his heart, so when that woman appeared, she obediently withdrew. However, unexpectedly, he abandoned his 'beloved' and instead frequently invited her.“Mr. Fu, didn't you say there was a contract to discuss?” He pressed her against the cold wall, continuously approaching: “If you were a bit uglier, perhaps I would want to talk contracts and drink tea with you, but you're so beautiful, I only want to talk love with you.”To him, Qiao Mo was like his most cherished treasure, and whenever others looked at her, he felt they were trying to steal her.
