During a trip to her boyfriend S 's beach house, Ai learns that his parents are pushing him to break up with Ai and date Sakurako, a girl they've chosen because of her family connections. Already uncomfortable in S 's lofty world of wealth and politics, Ai becomes even more self-conscious with the emergence of a new rival, and when S transfers to Sakurako's school, she fears that her nightmare may be coming true. Could he really have caved to his parents' demands? And will Ai's anxiety over losing her beau--along with the rampant peer pressure among the students--force her to "go all the way" before she's ready?
