Marie is smart enough to know that with Lucien's boost, her maximum mana and mana regeneration would be greater for a while.
But how could she ask for it in front of her mother and sister? So she used mental communication with him.
Although the girls who had no sex with Lucien yet had not good control of the mental communication, they were still able to use it with a short distance.
'Lucien... I ... I want...' Even using mental communication, Marie was embarrassed. But Lucien understood and spoke to calm her down.
'It's fine, Marie. A few kisses will be enough to improve your mana for some hours.'
Marie smiled sheepishly. She loved how caring Lucien is and understand her. She couldn't believe she thought so badly of him when they first met.
Of course, she still thought he was wrong about some things. She couldn't agree with his brutal way of acting, but she also knew that he has an incredibly gentle and caring side.
