A newlywed couple, Sota and Honoka, who have just bought a house with a loan, are visited by Kaito, Sota's boss and the president's son, who brings along his subordinates. Kaito relentlessly criticizes their small house, saying, "Why did you buy such a cramped house? If you had consulted me, you could have bought a much better one, haha." This almost makes Honoka explode with anger, but unable to oppose Kaito, Sota calms her down. Kaito sends Sota out to run errands, taking advantage of the situation to make a move on Honoka. A nauseating plot unfolds with an unprecedented betrayal!
