Intro
At a certain academy. Mashiro Shiragane, a beautiful girl perfect in both academics and sports, was obsessed over by four troublesome men, perhaps because of her unreachable, "flower on a high peak" aura. Neither the use of force, nor total rejection, nor reporting them to the police could stop their actions.
