Marian, who had only wanted a quiet and ordinary life, suddenly found her world turned upside down.

Because of her mother's remarriage, she gained a new stepbrother, but the problem was... He's overwhelming!

"I won’t let a single strand of your hair be harmed for as long as I live."

"Why are you making that promise?"

"If there's anything you wish for, tell me anytime."

"Please don’t stay cooped up at home. Go out, meet your friends, and socialize a little.

As if that weren’t enough, he even insisted on replacing the lavish carriage with a modest one, supposedly out of consideration for her dislike of attention, and spent a fortune making it happen.

Is he strange?

Or are all nobles this crazy?

Marian had thought her mother’s remarriage was simply about her getting a new husband, and had nothing to do with her.

But... can she really accept her new family?
