The older brother of the Onami family lives with her four younger sisters, Sora, Akane, Kohaku, and Sumi.
Having suffered from severe asthma when he was little, his daily routine is to “sleep with one of his sisters.”
One day, my parents, who are also researchers, ordered me to conduct a demonstration experiment of “immunity improvement by hugging.”
“Hug your sister with love for at least 10 seconds before going to bed every day.”
And if some conditions are not met, there will be no effect.
Aside from the confused older brother, the younger sisters decorated the condition with a frame in the living room as the five rules of hugging a woman.
