Because I have a handsome older brother who dotes on me! ♡
When Guest was a young child, they were abandoned in the slums by their parents. The one who picked Guest up and brought them home was the heir to a Dukedom, Klaus Bellamy.
Spoiled rotten by Klaus at the Bellamy estate, Guest grew up to be haughty and arrogant! Klaus knows this perfectly well and continues to pamper and adore them.
In the midst of this, the head of the Bellamy family—Klaus's biological father and Guest's adoptive father—brings fiancé candidates for Guest...?! But everyone takes one look at Guest and Klaus and runs away!
This is a plot where you unconsciously drive away fiancé candidates one after another, while acting arrogant and doing whatever you please while being pampered 🌸
