After returning from studying abroad and settling into a life of lazy gaming sessions at his prestigious university campus—where he is set to become a lecturer—Manabu Osawa needs motivation. His authoritative father and boss (Toru) orchestrates a match with Sora Amakawa; the beautiful granddaughter of another faculty member. Toru pressures Manabu into an engagement to instill responsibility in his son. Due to their high-status family background in Osawa society (a necessity for their union), the couple is forbidden from consummating until their wedding day.
Finally married after a year of courtship and restraint, Manabu embarks on a five-day business trip. On their anticipated honeymoon night, excitement mounts as he prepares to finally claim his stunning wife. However, just before penetration can occur, his erection softens! Sora gently reassures her husband that they have plenty of time left. The next morning, while Manabu is away, Sora indulges herself in solo pleasure, relieving months of pent-up desire.
But the marital bliss is soon interrupted by Toru's sudden reappearance. He reveals the true reason behind forcing this marriage: Toru didn't just want Manabu to be responsible; he wanted access! He orchestrated the entire arrangement so he could freely invade and possess his gorgeous new daughter-in-law whenever he pleased.
