Rio Hamasaki married Kazuyuki—the son of her former boss and current superior—under a seemingly perfect arrangement. The three of them live together in domestic bliss; the marriage between Rio and Kazuyuki is wonderful on the surface. However beneath this happy veneer lies a profound secret: Rio didn't marry him just for him! Her true desire was always to share a roof with her handsome father-in-law.
While Rio genuinely cares for Kazuyuki and enjoys their life as a unit under Shigeo’s guidance (who is also her boss), her heart belongs to his father. Due to the age gap between herself and Shigeo/her father-in-law figure, Rio has diligently suppressed her burgeoning feelings. She constantly tells herself that simply being near him is enough to satisfy her longing. But time spent in his presence has eroded every boundary she set,
leading to an undeniable surge of emotion. Now, Rio can no longer contain her yearning; she desperately wants more than just proximity. She craves it—she yearns for Shigeo to love her not just as his daughter-in-law, but as a woman worthy of his passion.
