How Does The My Happy Marriage Light Novel Differ From The Manga Adaptation?

"Did you ever, even once, imagine yourself loving me?" Sarah posed a hopeful question to Philip. "Don’t make me laugh, Sarah. Everything between us has been purely about pleasure and business.” Sarah had harbored feelings for Philip ever since she first saw him in a sports magazine.

She vowed to herself that she would find another man who would love, trust, and worship her like a queen. This is what she sought if she were to marry a second time.

Philip confronted Sarah in a ladies’ restroom, demanding, “Do not let other men touch you!” Sarah remained indifferent; her demeanor noticeably changed. “And what if I do?” she retorted. Philip’s tone grew menacing, “You won’t like what I’d do.” Unfazed, Sarah shot back, “Mr. Cornell, I’ve never liked what you’ve done, even in the past. There’s nothing new about that, and please stop whining like a baby,” before turning and walking away, disdainfully leaving him behind.
