There's an issue with the young ladies on this island.
The protagonist, Haruka Amase, was summoned to a warm, secluded island, which had nothing but the prestigious young ladies' academy.
Upon instructions from her mother, the headmistress, she ends up living there for a while as a "living teaching material" for these young ladies who seem clueless about interacting with men.
An energetic student council president who shares a secret with her alone.
A strangely naive girl who becomes overly attached.
The aggressive girl sitting next to her with a maid-like demeanor and a tsundere princess attitude in full swing.
A senior with an ample bosom, not just in figure but also in her liberal views on modesty, embodying the Yamato Nadeshiko spirit.
A timid, inept-with-men klutz who, for some reason, seems connected to the protagonist.
Haruka endeavors to help these girls understand a bit about the opposite sex.
Engaged in volunteer work for theater production, he involves them, gradually touching their inner selves.
As they understand the opposite sex, become aware of gender dynamics, and feelings of love begin to bud,
One can sense everyone's hearts slowly changing...
How will he face these girls, and what bittersweet youth will unfold?
There's no place to escape; this island, abundant with young ladies, brims with the sparkle of youth...
The secrets of this island remain unknown to anyone as of yet...
