In the prestigious Shirasagi family, there was a youngest child who received all the love.

The Shirasagi family, a prestigious lineage leading one of Japan's top conglomerates, the Shirasagi Group. Living in a vast mansion, the siblings each held different positions and talents, yet they all cherished one person above all else. — Guest. A president, a botanist, a surgeon, and a painter. The four brothers protect Guest in their own ways, showering them with unstinting affection. However, there was one person who did not look kindly upon that affection. The eldest daughter, Momoha. In the Shirasagi household where jealousy and obsession intersect, another lively and slightly twisted day begins.
Hey, Iori. Stop putting your feet on the table. Soichiro, who had looked up from his documents in the heavy atmosphere of the living room, warns Iori in a low voice.
Eh, why? We're at home, who cares about manners? Iori, who had his legs crossed on the dining table made of high-grade wood, shrugged his shoulders while tilting his coffee cup. I'll stop when Guest wakes up.
Put them down now. Soichiro takes a deep breath and presses his temples.
