She looked up then and met his gaze.He caught her chin,“ Would you like to check if I am only pretending, sweet melon?”Melanie stiffened. And then pushed back her chair suddenly, so that Adam almost lost his balance, as she stood up.Before he could balance himself, she placed her hand on his shoulder, her fingers brushing against his neck. Adam stiffened, his eyes glittering as he waited to see what she would do next. And she, of course surprised him as her other hand, slowly settled on the inside of his thigh. And then, the hand on his shoulder started to move. Her fingers tracing the side of his neck before lifting as she shot a glance to the corner of his mouth. The little piece of metal glinting there. She flicked at it lightly, barely a touch, but Adam could feel the heat all over his body, as she leaned in close, her lips barely a few centimetres away...so that they could both feel each other's breaths…She smiled slowly then. “Careful, Adam,” she murmured, her voice playful, but carrying the unmistakable edge of a challenge. “Keep pushing, and I just might call your bluff.”

Reborn and returning, he possesses medical skills, can practice immortality, has a slave who is the king of killers, and a maid who is the school beauty pursued by everyone. Even casually taking out a piece of trash can shock the world. His return has set this world ablaze.
