Lena Schneider is an up-and-coming young dressmaker. Her dress designs are popular among noble ladies, with one countess in particular favoring her and helping to spread her reputation.

At the recommendation of this benevolent countess, Lena reluctantly finds herself attending an arranged marriage meeting. Perhaps it was her ulterior motives – to return the favor, and perhaps even gain new connections if possible – that backfired, as her prospective partner turned out to be unexpectedly younger, and a minor to top it off.

An older brother and younger sister, oppressed by their adoptive family. When Lena learned why the brother was forced to attend the arranged meeting, she couldn't help but exclaim:

"Nobles are terrifying!"

Having met them, she couldn't just leave them be. Convinced she must use the power she possessed to save them, Lena, driven by a sense of "adult responsibility," decides to marry the brother and take in his sister.

It was strictly a marriage for their protection. When they eventually found someone they truly loved, Lena planned to send them off with a beaming smile... or so she thought, until she realized she was thoroughly enveloped by the siblings.

※Features a heroine (protagonist) who can crush anyone who breaks off her engagement on her own, and an older brother and younger sister who, despite being treated like doormats, rise up and fight back themselves.

※Serious elements are minor, the rest is a chaotic romantic comedy.
