During a trip to her boyfriend Sô'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 Sô's lofty world of wealth and politics, Ai becomes even more self-conscious with the emergence of a new rival, and when Sô 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?
