Reiko Sawamura plays Honami, who discovers her own underwear hidden beneath her son Junichi's clothes while cleaning his room—a place she rarely touches. Shocked and confused, she confronts him, only to be met with an unexpected confession: "I'm in love with you, Mom." Disbelieving at first, she tries to brush it off as a joke, but Junichi forcefully presses his lips against hers, determined to make his feelings known.
