This is the private school known as Ayanohara Academy.
A secluded flower garden where refined young traps from affluent families known as "he-iresses", come to form sisterly bonds and allow their quasi-yuri romances to flourish...
Despite cross-dressing being a venerated practice at the school, the main character Iori, a trap from an unaffluent background, refuses to do so invoking the wrath of the rigidly austere and stunningly beautiful student council president Mikage.
The volatile dude-butante drama between these two blossoms into into a full-on trap yuri romance, then soon becomes a forbidden love in more ways than one!
