Returning My New Brother

Marian, who just wanted to live a normal, quiet life, suddenly found her world flipped upside down. Her mother’s remarriage brought a new brother into her life, but the problem was… He’s way too overwhelming!!!"Until the day I die, I won’t let a single drop of trouble touch your hands." "Why are you making that promise?" "If there’s anything you want, just say it anytime." "Please don’t stay cooped up at home, go out and meet your friends, build some connections." And on top of that, to be considerate of me, who dislikes standing out, he even spent money to tone down a flashy carriage and make it plain?! Is this person weird? Or are all nobles this insane? I thought my mother’s remarriage only meant she’d have a new husband, and it had nothing to do with me. But now… Can I really accept this new family?
