The protagonist's mother remarries a man slightly younger than himself, and though he tries to maintain a respectful distance as her son, he finds himself increasingly drawn to the man's youthful appearance. After the marriage, he notices his mother's demeanor becoming noticeably brighter, as if she's turned back the clock and regained her youth. Gradually, he begins to see her not as a mother, but as a woman. Using his stepfather's business trip as an excuse, one night he reaches for his mother's breasts—sparking feelings he's never experienced before.
