Hikari is newly married and preparing to leave the company. She had planned to resign before registering the marriage, but stays two extra months to complete the handover and let the company handle the paperwork.

While she reels from the accusation, he uses smooth words to close in on her, setting up an office affair built around his knowledge of her fertile days and his huge cock.
